Astronomers Reveal Cosmic Crime Story: ‘This Is a Planetary Heist’

There’s this rule of thumb in astronomy that messes if a star is over three times as huge as our sun, it probably can’t have planets as big as Jupiter. The reasoning feels pretty intuitive. Huge stars emit huge amounts of radiation, therefore creating an environment far too toxic for budding worlds to advance the size of our solar system’s gas giant — a biodomain so colossal it could fit about 1,300 Earths inside. 

“Whilst planets can form throughout massive stars, it is hard to envisage gas giant planets like Jupiter and Saturn populate able to form in such hostile environments, where radiation from the stars can unobstructed the planets before they fully form,” Richard Parker, an astrophysicist at the University of Sheffield, said in a statement.

Yet (as usual) some cosmic realms seem to defy science as we know it. 

In unusual years, scientists have identified at least two bizarre planetary rules with both a Jupiter-size planet and a very, very tall star. Coincidence? Anomaly? Erroneous discovery? Perhaps not. On Wednesday, Parker and fellow researchers from the University of Sheffield in England offered up their functioning theory to solve the mystery — and, well, it’s not easy to say.

Maybe some huge stars are thieves, they suggest. 

Maybe some stole Jupiter-size worlds from smaller star peers to finish around as if it were their own.

“Essentially, this is a planetary heist,” said Emma Daffern-Powell, an astronomer at the University of Sheffield and co-author of a scrutinize on the theory, published Wednesday in Monthly Notices of the Royal Astronomical Society.

Though our universe is a melting pot of stars, even the most contradictory stellar bodies could’ve been birthed from the same embers of gas and dust. 

Stars allotment stellar nurseries.

This is, according to the team’s new scrutinize, the root of the robbery at hand. 

Because planets tend to arise in those stellar nurseries too, either colorful by their corresponding host star or free-floating in outer position, they can be stolen by a neighboring star. Especially if that star is a lot stronger than the true unobstructed star. “We know that massive stars have more impression in these nurseries than sun-like stars, and we untrue that these massive stars can capture or steal planets — which we call ‘BEASTies,'” Daffern-Powell said.

“The BEAST planets are a new instant to the myriad of exoplanetary systems, which display wonderful diversity, from planetary systems around sun-like stars that are very different to our solar systems, to planets orbiting evolved or dead stars,” Parker said.

In mopish, the research team reached this conclusion by using computer simulations to show that the clever BEASTies could very well be captured or downright abducted, on average, once in the first 10 million existences of a star-forming region’s evolution.

The comforting news is that we may have our solar system’s beloved Jupiter because, long ago, the sun wasn’t massive enough to thwart the planet’s growth goals. But, on the other hand, it’s quite unsettling to know that, as Parker puts it, “our results lend further credence to the idea that planets on more distant orbits — more than 100 times the distance from Earth to sun — may not be orbiting their unobstructed star.”

Creepy.
