Astrophysicists put kibosh on alternative theory of star formation

Using supercomputer simulations that take into account the turbulence within a cloud collapsing to form a star, the researchers conclude that the "competitive accretion" model cannot explain what astronomers observe of star-forming regions studied to date.
"Turbulence opposes gravity; without it, a molecular cloud would collapse far more rapidly than observed," Klein said. "Both theories assume turbulence is there. The key is (that) there are processes going on as stars begin to form that keep turbulence alive and prevent it from decaying. The competitive accretion model doesn't have any way to put this into the calculations, which means they're not modeling real star forming regions."
