Oct. 27	Tinsley Scholar: Interstellar Group (visiting: Oct 25-31) "The Impact of Stellar Feedback on Molecular Clouds" Low-mass stars influence their surroundings through a variety of feedback processes. However, because they are less energetic than high-mass stars, their contributions are often ignored. In this talk, I will discuss numerical simulations including protostellar outflows and winds from main sequence B-type stars. I will evaluate the role of these processes in the star formation process, and I will demonstrate that such feedback has important implications for the stellar initial mass function, the star formation efficiency of dense gas, and cloud turbulence. close Stella Offner Affiliation: University of Massachusetts, Amherst host: Neal Evans
