Public Release:  How to build a very large star

University of Toronto

Now, a group of researchers led by two astronomers at the University of Toronto suggests that baby stars may grow to great mass if they happen to be born within a corral of older stars -with these surrounding stars favorably arranged to confine and thus feed gas to the younger ones in their midst. The astronomers have seen hints of this collective feeding, or technically "convergent constructive feedback," in a giant cloud of gas and dust called Westerhout 3 (W3), located 6,500 light years from us. Their results are published in April in The Astrophysical Journal.
