Scientists show massive stars can capture planets – transcontinental times

United kingdom: According to a recent study, large stars in the very crowded stellar nurseries where most stars are created can steal or trap Jupiter-sized planets.

Recently Found Studying the abundance of B . exoplanets (BEAST) Planets have a new explanation, according to researchers from the University of Sheffield. These are Jupiter-like planets located far from the powerful stars – hundreds of times farther than the distance between the Earth and the Sun.

Because massive stars generate so much ultraviolet radiation, which prevents planets from growing to the size of Jupiter, the largest planet in our solar system, their birth has so far been somewhat of a mystery.

Dr Emma Davern-Powell, University of Sheffield’s Department of Physics and Astronomy, who is a co-author on the paper, added: “Our previous research has shown that in stellar nurseries, stars can steal planets from other stars or capture what we call ‘floating’ planets. We discovered that these massive stars can grab or steal planets, which we refer to as ‘besties.’ We know that massive stars have more influence in these nurseries than do sun-like stars.

This is basically a planetary theft. We’ve demonstrated through computer simulations that these BEASTies are often stolen or captured once over the first 10 million years of the star-forming region’s history.

Incredibly diverse exoplanet systems now include the BEAST planets, according to Dr. Richard Parker, lecturer in astrophysics at University of Sheffield. Planets that orbit advanced or dead stars into sun-like star systems are very different from our own solar system.

At least two Jovian super-planets have been found in the habitable zone of powerful stars through the BEAST collaboration.

It’s hard to imagine how gas giant planets like Jupiter and Saturn could form in such extreme conditions, where radiation from stars can evaporate planets before they are fully formed, even so planets can form around massive stars.

However, our models show that these planets can be captured or captured in orbits strikingly similar to those seen in BEASTies. Our findings support the hypothesis that planets with orbits greater than 100 times the distance between the Earth and the Sun may not revolve around their parent star.

The study by Dr Richard Parker and Emma Davern-Powell at the University of Sheffield is part of a larger effort to determine how common planetary systems similar to ours are compared to tens of thousands of other planets. Milky Way Systems.
