Scientists trying to figure out how massive stars end up with large planets around them, despite the tremendous radiation they blast out, may have their answer.
"Whilst planets can form around massive stars, it is hard to envisage gas giant planets like Jupiter and Saturn being able to form in such hostile environments, where radiation from the stars can evaporate the planets before they fully form," Parker added.
The new research posits that these massive BEASTies didn't form in their current systems at all but instead were snatched from around smallerin a stellar nursery, a region where rates of star formation are particularly high. The pair of scientists behind the work reached this conclusion by simulating the conditions in stellar nurseries, which showed that planets captured from these regions can settle into orbits similar to those of observed BEASTies.
The duo's previous research had already shown that massive stars within stellar nurseries could ensnare planets from other stars or rogue free-floating planets that do not orbit a star. But this research makes it clear these snatched worlds can become 'BEASTies.' "Essentially, this is a planetary heist," Emma Daffern-Powell, an astronomer also at the University of Sheffield, said in the same statement."We know that massive stars have more influence in these nurseries than
-like stars, and we found that these massive stars can capture or steal planets — which we call 'BEASTies.'"
