Talk Title: Condensation, star formation and accretion in quasars and Sgr A*.
Abstract: In light of the recent observations of Sgr A*, we consider two processes that are vital to the evolution of the accretion flow and black hole growth in AGN. First is condensation of hot material that builds a thin accretion disk. Second is star formation in a self-gravitating accretion disk. The latter may be so efficient as to deplete the accretion disk much faster than the black hole could consume the disk, thus starving the black hole. We show however that continuing star formation and condensation result in disks that are able to transfer most of their mass into the black hole. Among other interesting effects connected with star-disk interactions may be the X-ray/NIR flares observed in Sgr A*.
