Molecular Cloud evolution: Regulation of the Star Formation Rate by feedback from massive stars

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.
