Feedback & Self Regulation in Star Formation: Driver of the Galactic Ecology

Friday April 21, 2017
4:00 pm

 Presenter:  Professor John Bally, Astrophysical and Planetary Sciences, University of Colorado, Boulder
 Series:  Physics and Astronomy Colloquium
 Abstract:  The energy and momentum injected by forming stars into the surrounding interstellar medium (ISM)limits the star formation efficiency, the fraction of the parent cloud's mass converted into stars. I will describe the "feedback ladder" of ever more powerful processes which drive the "Galactic ecology"; protostellar outflows, soft-UV, ionizing-UV, radiation pressure, stellar winds, and explosive transients such as supernovae. I will argue that chaotic N-body dynamics and feedback dominate the properties of the stars, clusters, and associations produced by the star formation process.
