Vince can't send a post for the moment, but has an interesting article to propose:

"Astrophysicists at the University of California, Berkeley, and Lawrence Livermore National Laboratory (LLNL) have exploded one of two competing theories about how stars form inside immense clouds of interstellar gas....Competitive accretion is the big theory of star formation in Europe, and we now think it's a dead theory...In competitive accretion, the cores are seeds that grow to become stars; in our picture, the cores turn into the stars...

Star formation is a very rich problem, involving questions such as how stars like the sun formed, why a very large number of stars are in binary star systems, and how stars ten to a hundred times the mass of the sun form," he said. "The more massive stars are important because, when they explode in a supernova, they produce most of the heavy elements we see in the material around us."
