[72.10] Feedback and the Star Formation Efficiency in Young Galaxies

S. D. Murray (Lawrence Livermore National Laboratory), D. N. C. Lin (University of California, Santa Cruz)

We present models of star formation in small systems, designed to examine the role of feedback in determining the star formation efficiency within young galaxies. The models include thermal and dynamical feedback mechanisms due to photoionizing radiation and supernovae. Also included are appropriate time delays between star formation and the onset of the feedback. The results of both one-zone and multi-zone models will be presented. This work was performed in part under the auspices of the U.S. Department of Energy by the University of California Lawrence Livermore National Laboratory under contract No. W-7405-Eng-48.
