Star-Disk Interactions in Active Galactic Nuclei
Galaxies are classified as Active Galactic Nuclei (AGNs) if the supermassive black hole (SMBH) at their center is actively accreting matter through an accretion disk. Stars and stellar objects orbiting the galaxy will experience a drag force as a result of their interaction with the disk, capturing orbits that are initially inclined with respect to the plane of the disk and causing the migration of fully embedded orbiters towards the SMBH. The formation of a population of embedded stellar objects, can fuel mergers detectable in gravitational waves with LIGO-Virgo and LISA. The goal of this project is to study the said mechanism of star-disk interactions in AGNs performing high-resolution N-body simulations with the Nbody6++GPU code.
