WARPED CIRCUMBINARY DISKS IN ACTIVE GALACTIC NUCLEI
WARPED CIRCUMBINARY DISKS IN ACTIVE GALACTIC NUCLEI
We study a warping instability of a geometrically thin, non-self-gravitating disk surrounding binary supermassive black holes on a circular orbit. Such a circumbinary disk is subject to not only tidal torques due to the binary gravitational potential but also radiative torques due to radiation emitted from an accretion disk around …
