Dynamical evolution of dense star clusters in galactic nuclei
Original language description
By means of direct numerical N-body modeling, we investigate the orbital evolution of an initially thin, central mass dominated stellar disk. We include the perturbative gravitational influence of an extended spherically symmetric star cluster and the mutual gravitational interaction of the stars within the disk. Our results show that the two-body relaxation of the disk leads to significant changes of its radial density profile. In particular, the disk naturally evolves, for a variety of initial configurations, a similar broken power-law surface density profile. Hence, it appears that the single power-law surface density profile PROPORTIONAL TOR -2 suggested by various authors to describe the young stellar disk observed in the Sgr A* region does not match theoretical expectations.
