Abstract

Two modes of star formation are involved to explain the origin of young stars near Sgr A. One is a disk-based mode, which explains the disk of stars orbiting Sgr A. The other is the standard cloud-based mode observed in the Galactic disk. We discuss each of these modes of star formation and apply these ideas to the inner few parsecs of Sgr A. In particular, we focus on the latter mode in more detail. We also discuss how the tidal force exerted by the nuclear cluster makes the Roche density approaching zero and contributes to the collapse of molecular clouds located tens of parsecs away from Sgr A.
