Astronomers uncover “planetary incursion”.

Stars can hijack planets from other stars, so to speak. This is how big stars get their BESTies.

stars that more than three times as much mass have like our sun, have no planets larger than Jupiter. That’s what people thought for a long time. The stars shine so much ultraviolet radiation from that gas planet gradually removed will. However, according to astrophysicist Richard Parker, it’s still possible for these stars to have large satellites – by having planets from other stars steal.

Gas planets evaporate before they form

“While planets can form around such massive stars, gas giants can Jupiter or Saturn very rare. They evaporate before they can fully develop,” the University of Sheffield researcher says in one sending. However, there are some exceptions that seem to contradict this rule.

Scientists have discovered at least 2 Planetensystemewho made a big gas planets and one massive star exist. According to Parker and his team, this could be a kind of “theft” act.

“Abduction” from the cradle

This theft already happens at the emergence the Stars. These are formed in interstellar gas clouds, which can encompass several million solar masses. In these birthplaces of the stars, however, not only stars are formed, but also planets.

These planets can sometimes be of one neighboring starwhich is just emerging, can be stolen – especially if it is large and high attraction Has. “We call these stolen planets BEASTies,” says co-author Emma Daffern-Powell. The name BEAST comes from the “B-star Exoplanet Abundance STudy‘ where the two extraordinary planetary systems were discovered.

Jupiter is not a BEAST

according to the Astronomers’ computer calculations have the stars the planets in first 10 million years their existence in a way kidnapped. In cosmological terms, this is practically newborn age, but our solar system is already around 4.6 billion years alt.

“The BEAST planets are a new addition to the myriad of exoplanetary systems that exhibit incredible diversity,” says Daffern-Powell. At our Jupiter however, it is not one BEASTie. Our sun was not big enough when it was formed to limit its growth.
