Molecular Cloud evolution: Regulation of the Star Formation Rate by feedback from massive stars Manuel Zamora-Aviles CRyA-UNAM, Morelia, MX
We present MHD simulations including radiative transfer and magnetic field of the evolution of molecular clouds formed by two colliding warm neutral medium flows. These clouds eventually begin to form stars/clusters and also to collapse globally. We found that the massive stars formed, effectively stop the global collapse evaporating and dispersing a large fraction of dense gas, thus regulating the rate and efficiency of star formation.
