The presence of young, massive stars suggests a substantial mass inflow event to the Galactic Center approximately 6 million years ago. Numerical models of gas inflow toward a supermassive black hole show that star formation may occur in such an environment through the growth of a gravitationally unstable gas disc of high eccentricity. As a refinement on previous calculations, our models include the effects of radiative feedback on disk and star formation during such an accretion episode. Taylored to conditions envisaged for the Galactic center, the models suggest that radiative feedback from AGN-like activity in the Galactic center will not inhibit circum-nuclear star formation arising from a massive inflow event.
