SUMMARY:The dynamics of parsec-scale eccentric stellar disks around SMBHs 
 in galactic nuclei: disk disruption mechanisms\, tidal disruption events a

DESCRIPTION:We study the dynamics of eccentric parsec-scale stellar disks 
 around supermassive black holes (SMBHs) in galactic nuclei using our novel
  post-Newtonian N-body code BIFROST. The simulated eccentric disks (Mdisk<
 Msmbh) are unstable and rapidly disrupt in <1.5 Myr. The disk disruption n
 aturally results in a formation of a milliparsec stellar population around
  SMBHs due to disk migration and binary disruptions via the Hills mechanis
 m. The eccentric disk disruption can considerably boost the tidal disrupti
 on event rate of galaxies for a short period of ~1Myr. Finally\, we discus
 s the implications of our results for understanding the structure of the M
 ilky Way centre.
