Stationary massive disks around black holes: realistic equation of state and bifurcation
arXiv:2103.15701 · doi:10.1103/PhysRevD.104.024005
Abstract
We study stationary and axially symmetric black hole-disk systems, assuming a combination of the DD2 and Timmes-Swesty equations of state and a three-parameter family of rotation laws. There exist two branches of solutions that are shown to bifurcate, for a suitable specific entropy and a parameter in the rotation law. Low entropy nuclear matter allows for the existence of moderately massive Keplerian disks.
