22 September 2005Speaker: Steven Stahler (UC Berkeley) Title:Unsolved Problems in Star Formation Abstract: There are still major unsolved questions in the theory of star formation. How do clusters form out of large molecular clouds? How do the disks around individual stars accrete onto those objects? In addressing such issues, theorists generally assume that processes occur on a rapid (dynamical) time scale. Yet observations clearly demonstrate otherwise. Dynamical proceses are easier to model numerically, but a quasi-static picture is often more appropriate. I discuss how this realization can help address the two specific problems of cluster formation and disk accretion. In the latter area, fresh theoretical ideas and the powerful capabilities of the SMA should lead to significant progress in the near future.
