Description
The centers of galaxies like our own are usually dominated by disk structures at scales of tens to hundreds of parsecs - and thus orbits near the galactic center are in axisymmetric potentials which conserve only one component of their angular momentum if an orbit comes close enough the central super massive black hole there can be disruptions, leading to the creation of hyper-velocity stars, tidal disruption events or extreme mass ratio insprials in this talk i'll show how some orbit families (particularly chaotic ones) in such a potential can lead to plunges in the total angular momentum of stars, making close passages to the SMBH possible - i will discuss the types of orbit that will lead to disruptions and give initial estimates for the rates.
