"Turbulent Cooling Flows in Molecular Clouds" by Myers & Lazarian (98 ApJ 507, L157) versus "Photoionization Regulated Star Formation" by McKee (89 ApJ 345, 782)

Myers and Lazarian propose a very interesting way to form cores in convergent flows by turbulent dissipation of mhd wave pressure, which acts more efficiently at high densities. This leads to an underpressure at the higher densities, which accelerates the flow along. The upshot is that one can collapse cores in their framework in less than an ambipolar diffusion time, which may help resolve the observed underabundance of starless cores in Taurus.
