Feedback and the Initial Mass function
Abstract
I describe a turbulence-inspired model for the stellar initial mass function which includes feedback and self-regulation via protostellar outflows. A new aspect of the model provides predictions of the star formation rate in molecular clouds and gas complexes. A similar approach is discussed for self-regulation on kiloparsec scales via supernova input, and an expression is presented for the global star formation rate that depends on the turbulent pressure of the interstellar medium.
