The radiation from massive stars shapes planetary systems

The radiation from massive stars shapes planetary systems

Massive stars can “evaporate” the material necessary to form giant planets like Jupiter, according to the first observation of the phenomenon, reported in a study published in the journal Science (New Window).

An international team of astronomers led by French researchers from the National Center for Scientific Research (CNRS) observed the emerging planetary system d203-506 to confirm the predictions of theoretical models.

This small, very young system lies on the edge of the Orion Nebula and theoretically has everything it takes to produce at least one gas giant like Jupiter or Saturn, a planet consisting essentially of hydrogen and helium.

The modest star that d203-506 hosts at its center is surrounded by a protoplanetary disk, in this case a gas cloud, which theoretically serves as raw material for the formation of a gas planet.

But unfortunately for it, the small system is exposed to very strong ultraviolet radiation emanating from massive and very close stars in the Trapezium Cluster. According to a press release from the CNRS, stars are about ten times more massive than the Sun and, above all, 100,000 times more luminous.

Their radiation heats the gas cloud in a phenomenon known as photoevaporation. It brings the hydrogen molecules in that cloud to temperatures so that they begin to circulate at enough speed to escape the star's gravitational pull. Before it dissipates far into interstellar space.

The result of this radiation is enough to remove gas from the (protoplanetary) disk in less than a million years, the study says. And therefore fast enough to influence the formation of giant planets in the disk, she concludes.

The observation of the phenomenon was made possible by combining data from the James Webb Space Telescope and the terrestrial radio telescope ALMA.

Those from Dr. Mobile application EZResus, developed by Frédéric Lemaire of Charles-Le Moyne Hospital and facilitating the administration of medication to patients in emergency situations, has won the Canadian Space Agency's Deep Space Healthcare Challenge, the Charles-Le Moyne Foundation announced February 28.

Dr. Lemaire worked on the design of this application for eight years in collaboration with around twenty of his colleagues. The tool allows the medical team to “quickly find the right dosage, the right concentration and the appropriate rate of administration of each medication based on different patient characteristics,” reports the Integrated Health and Social Services Center of the Montérégie-Centre (CISSSMC).

“Medicine worked very well before we used it, but what it specifically changes is that it takes away the mental burden of concentrating on the patient,” said the doctor at the launch in December 2021. It is certain that we ” We’re still checking, but the environmental stress level is going down a lot.”

Dr. Lemaire received support from the Charles-Le Moyne Hospital Foundation and the Charles-Le Moyne Research Center. The application, used by 5,000 doctors in 29 countries, can administer nearly 100 medications in intensive care for children and adults.

The goal of the competition is to “develop new health technologies that could be used in remote communities and by astronauts on missions,” according to the foundation.

“This is absolutely incredible news! It's a childhood dream come true! What a tremendous recognition, but above all what an extraordinary opportunity for us to continue our work to develop the best possible application and distribute it to as many communities as possible and, tomorrow, to astronauts on missions in space. “In the end, what really matters is saving more and more lives in the first hour of resuscitation,” emphasizes Dr. Frédéric Lemaire in a press release.

The best US bond ETFs

Do investors need bonds in their portfolios?

The question is personal. Investors with goals within three to 10 years (for example, buying a new home, starting a business, or retiring within the next decade) likely need it. The same applies to those who are already retired. Bonds are also preferred by investors who do not want to invest 100% in stocks, regardless of their investment horizon.

Exchange-traded funds that focus on fixed income securities can be a good way for investors to gain exposure to bonds. Here are some reasons:

• Many ETFs are transparent – ​​most track indexes with very specific maturity and credit characteristics – and offer few surprises.

• The best ETFs are cheap, which is even more important when investing in bonds than stocks: Any percentage more in fees means a percentage less return, and returns are generally harder to achieve with bonds than with stocks.

• ETFs are easy to buy and sell.

A good place to start when looking for the best bond ETFs is the Morningstar Medalist Rating. The highest-rated ETFs (Gold) are those that we believe are most likely to outperform across an entire market cycle.

Here is the list of the best bond ETFs, divided into three main groups: core bond funds, short-term bond funds and specialty bond funds.

The 5 Best Core US Bond ETFs to Buy Now

These ETFs all fall into one of Morningstar's intermediate-term bond categories and receive our highest Gold Medal Rating with 100% analyst coverage as of February 2024.

– Fidelity Total Bond ETF (FBND)

– iShares Core Total USD Bond Market ETF (IUSB)

– iShares Core US Aggregate Bond ETF (AGG)

– Vanguard Tax-Exempt Bond Index Fund (ETF)

– VTEB Vanguard Total Bond Market ETF (BND)

The top-rated ETFs on this list would be excellent choices for hedging the bond portion of an investor's portfolio, provided the investment goals are more than five years away.

iShares Core US Aggregate Bond ETF And Vanguard Total Bond Market ETF are listed by Morningstar as intermediate-term core bond ETFs, meaning they invest in a mix of investment-grade U.S. bonds, including government bonds, corporate bonds and securities. Fidelity Total Bond ETF And iShares Core Total USD Bond Market ETF are listed as medium-term core-plus bond ETFs. In addition to investing in investment-grade U.S. bonds, these funds have greater flexibility to also purchase high-yield corporate bonds, bank loans and emerging market debt.

Finally, this Vanguard tax-exempt bond ETF is the highest-rated municipal bond ETF covered by Morningstar. This is a good option for those who invest in taxable accounts and are in high tax brackets.

If none of these ETFs are right for you, see The Best ETFs and Where They Place in Your Portfolio for other top-rated ETFs.

7 Best Short-Term US Bond ETFs in 2024

These ETFs all fall into the Ultra-Short Bond or Short-Term Bond categories and receive our highest Gold Medal Rating with 100% analyst coverage as of February 2024.

– JP Morgan Limited Duration Bond ETF (JPLD)

-Pimco Enhanced Short Maturity Active ESG ETF (EMNT)

-Pimco Enhanced Short Maturity Active ETF (MINT)

-Schwab Short-Term US Treasury ETF (SCHO)

-SPDR Portfolio Short Term Treasury ETF (SPTS)

-Vanguard Short-Term Corporate Bond ETF (VCSH)

-Vanguard Short-Term Treasury ETF (VGSH)

The top-rated ETFs on this list are good choices for those who want to invest in bonds but plan to use these investments in the next few years.

THE Pimco Enhanced Short Maturity Active ETF and that Pimco Enhanced Short Maturity Active ESG ETF Both can be considered ultra-short-term bond ETFs. ETFs in this category prefer high-quality bonds with a maturity of less than one year.

THE Vanguard Short-Term Corporate Bond ETF belongs to the category of short-term bonds, while the Schwab Short-Term US Treasury ETF and that Vanguard Short-Term Treasury ETF both belong to the category of short-term government bonds. As the category name suggests, short-term government ETFs focus exclusively on short-term U.S. government bonds, while short-term bond ETFs may also invest in high-quality corporate bonds rather than Treasury bonds. In both cases, ETFs prefer bonds with a maturity between 1 and 3 years.

The 6 best ETFs specializing in US bonds

These ETFs all fall into one of Morningstar's specialty bond categories and have received our highest Gold Medal rating with 100% analyst coverage since February 2024.

– Schwab US TIPS ETF (SCHP)

– T. Rowe Price Floating Rate ETF (TFLR)

-Vanguard Intermediate-Term Corporate Bond ETF (VCIT)

-Vanguard Long-Term Bond ETF (BLV)

– Vanguard Long-Term Corporate Bond ETF (VCLT)

– Vanguard Short-Term Inflation-Protected Securities ETF (VTIP)

The highest-rated ETFs on this list are so-called “satellite” positions in a bond portfolio. In other words, these are not core holdings, but an investor can hold these ETFs to supplement a bond portfolio, undertake a tactical restructuring, or fulfill another specific interest.

The list includes the two best bond ETFs for inflation protection: Schwab US TIPS ETF And Vanguard Short-Term Inflation-Protected Securities ETF. Both fall into the category of inflation-protected bonds and invest in securities whose principal value is adjusted according to the rate of inflation, which may be of interest to some investors (particularly retirees).

The other funds on the list favor different types of bonds (corporate bonds, floating rate securities). Long-term funds, such as Vanguard Long-Term Bond ETF and that Vanguard Long-Term Corporate Bond ETF, are very sensitive to interest rate changes and are very volatile compared to bond funds. They can be used to benefit from falling interest rates or as a long-term debt protection tool.

Saint-Cyprien: Local businesses to preserve

BUSINESS. The GJ gas station has been part of the landscape of the municipality of Saint-Cyprien for 27 years. The owners, Ghislain Lapierre and Julie Morissette, hope their local business, the last in the area, will survive into the future as it is up for sale.

“We are proud of what we have built over the last 27 years. “We hope to find a mechanic who is interested in buying the business and taking it over from us,” said the couple, who opened the business on August 27, 1997.

Entrepreneurs at heart, Ms. Morissette and Mr. Lapierre purchased the property on which they built their garage in April 1997. There was a snack bar there that was bankrupt at the time. Ms. Morissette operated on it until the garage opened.

“We had four children aged 3 to 7 at the time and it was now costing us an income. After the garage opened, the snack bar was torn down because we couldn't have two stores on the same property. We started from scratch,” says Ms. Morissette, adding that their great adventure continued 27 years later, they always worked together in the family business.

Business was always good, the couple remembers, even though the city of Saint-Cyprien is not the most populous. “A lot of people encourage us even though we are in a small community. “To this day, we still place a lot of emphasis on rust protection, alignment and automotive certification because there aren’t many of us who do that,” Ms. Morissette continues.

Julie Morissette and Ghislain Lapierre indicate that the sales process is initiated with a real estate agent, with the aim of keeping the garage in excellent condition and having an active clientele that will allow the buyer to make his payments without any problems. “If he works, he will earn money and live well. We have a core customer base that is established and loyal, and I stay with the person for as long as it takes to transition and introduce them to the new buyer,” says Mr. Lapierre.

They have reduced their opening hours slightly in recent years to think about their health. “We decided a few years ago to close at 6 p.m. on Thursdays and Fridays so that Ghislain could continue because he has back problems from years of working as a forestry worker,” says his wife.

Start from scratch

When Ghislain Lapierre opened his workshop in 1997, he had no training as a car mechanic. However, he had acquired some basic knowledge by regularly servicing the forestry machines he had previously worked on.

“I also worked for several years at Réal Racine in Sainte-Justine, where I maintained the plows and compressors. In the first few years I worked 7 days a week in the workshop and, in addition to the online training, attended car mechanic courses in Lévis or Montmagny, then at CIMIC. This gave me time to seek out the knowledge I was missing,” he explains.

The couple says they have worked hard all these years. “We lived a good life, we were able to pay for our four children's education, we paid for the cars so they could go to school, we did everything we could for them, now it's time for ours “To think about life,” he continues.

“We want the buyer who comes forward to be as proud as we are because we have invested a lot in this business. We would be disappointed if the business closed after the sale because we started from scratch. In the first few years we worked 7 days a week. We would enter here at 7:30am and stay until 8 or 9pm depending on the day. We didn’t count the hours,” says Ms. Morissette, adding that there was even a kitchen above the main entrance that her father had set up.

“We raised our children here. They came here for dinner and came back here after school. We did our homework upstairs and even had dinner here some nights. They saw us working through the window, even on weekends. They learned everything here, everyone spent gas and worked in the evenings. They still thank us today for everything we showed them because they all have good jobs and enjoy working. They gave us nine grandchildren, that is our pride,” the couple mentions.

People's support is needed

Julie Morissette recognizes that gasoline sales could be better if they are good, because many Saint-Cyprien residents fill up where they work. “Gasoline is good, but it could be better if everyone joined in. It's a question of volume. The residents of Saint-Cyprien come less for the petrol than for the mechanics. For aesthetic reasons, we have a lot of outside and also serve them petrol,” she adds cautiously.

“It makes us proud to see that our business is still operating and is the only truly local business in the community. People's priority is to save gas. It's social and we help people who need it. Everyone uses the service they need. If we were to close it would be sad because we no longer have a school or a grocery store. »

The couple mentions that the arrival of newcomers taking French courses in Saint-Cyprien has also been very beneficial for them, as they make up a significant part of their clientele. “We have developed a good bond with them, but you have to take the time to listen to them. They ask a lot of questions and you have to take the time necessary for them to understand what is being explained to them, because you have to remember that they are learning French. They have learned to trust us. If necessary, we use the mobile phone,” explains Mr. Lapierre.

Development potential

Julie Morissette and Ghislain Lapierre believe their company offers development potential that would allow two people to work together and make a good living. “People would rather repair their cars than buy a new one. This helps companies like ours because people want to keep their cars,” says Ms. Morissette.

The couple added that their property is large enough to even allow a supermarket to be added to the current building. “Until that happens, more people will be needed in Saint-Cyprien,” concludes Mr. Lapierre.

The urban planning advisory board welcomes three new members

The urban planning advisory board welcomes three new members

Thetford Mines Parish Council has appointed three new members to its town planning advisory board. This approach follows the call for applications addressed to the population a few months ago.

Together with the two elected officials already in office, these five people officially constitute this committee, whose task is to provide the Council with opinions on the various requests from citizens on urban planning and regional development issues.

Of the three new members, two accepted a two-year mandate, namely Logann Morissette, coordinator of the Héritage Center-Ville organization, and J. Chantal Roy, retired project manager. Luc Falardeau, a citizen involved in various trail development projects, will assume this role for a period of one year.

“We are very pleased about citizens’ interest in urban planning and urban development. These new members have skills that will enrich discussions and recommendations to the council. “I would of course like to thank the outgoing members for their commitment over the last few years,” said Anthony Bilodeau, President of the Urban Planning Advisory Committee, President of the Urban Planning and Economic Development Commission and City Councilman.

Remember that the Town Planning Advisory Board appointed by the local council meets 16 times a year with one or two meetings per month.
