Massive Star Formation: A Tale of Two Theories
Mark Krumholz, Princeton
abstract   bio

Stars with masses above about 20 solar masses have short Kelvin-Helmholtz times that enable them to reach the main sequence while still accreting from their natal clouds. The resulting nuclear burning produces a huge luminosity and a correspondingly large radiation pressure force on dust grains suspended in the incoming gas. Early work suggested that this effect imposed an upper limit of about 20 solar masses on stars forming from gas with the normal galactic dust abundance, and even more recent two-dimensional simulations and analytic calculations have not yet been able to explain the existence of stars of 50 solar masses and larger. In this review I will present the current state of this long-standing problem, and discuss the two primary approaches to solving it. One holds that the most massive stars form by direct collisions between lower mass stars and their disks. The other approach is to see if the radiation barrier can be overcome by a more accurate and realistic treatment of the radiation-hydrodynamic accretion process. I will discuss the theoretical background to each model, the observational predictions that can be used to test them, and the substantial parts of the problem that neither theory has fully addressed.
