One of the most powerful supercomputers on Earth has simulated the interiors of low mass stars, helping scientists understand their evolution. As these stars exhaust their hydrogen fuel, they eject helium into their surrounding neighbourhood. But the quantities of this ejected helium didn't match observations by telescopes. This new simulation shows that stars can actually destroy some of this helium inside the star, instead of ejecting it into space.

There are many papers that get published about computer simulations of stars and other astrophysical phenomena. It's nice to see one summarized on Universe Today. Thanks! This is a cool one.

How much suspicion of the validity of their model is reasonable. Even though their results are plausible, they provided little description other than pointing to its three-dimensionality.
