Stationary massive disks around black holes: Realistic equation of state and bifurcation

Wojciech Kulczycki et al.

Summary: In this study of stationary and axially symmetric black hole-disk systems, two branches of solutions are found to bifurcate based on specific entropy and rotation law parameter. Low entropy nuclear matter allows for the presence of moderately massive Keplerian disks.

Magnetized discs and photon rings around Yukawa-like black holes

Alejandro Cruz-Osorio et al.

Summary: This study presents stationary solutions of geometrically thick discs with a toroidal magnetic field distribution around a nonrotating black hole in the background of f(R)-gravity, showing different characteristics based on the strength of the magnetic field and the model's parameter delta. The comparison with general relativity reveals significant changes in the black hole space-time solution for high values of delta, impacting the morphology and thermodynamical properties of the discs. By analyzing the size of the photon ring produced by a distant source, constraints on the f(R)-gravity model parameters can be placed based on observations of the light ring in M87 and SgrA* by the Event Horizon Telescope.

Stationary models of magnetized viscous tori around a Schwarzschild black hole

Sayantani Lahiri et al.

Summary: This study explores stationary solutions of magnetized, viscous thick accretion disks around a Schwarzschild black hole, focusing on the role of black hole curvature in the shear viscosity tensor and their combined effect on the solutions. The effects of shear viscosity and curvature are particularly noticeable near the cusps of the disks, with less significant shifts in cusp locations for highly magnetized disks. This research may have implications for dynamical stability of constant angular momentum tori, especially in the context of runaway instability in inviscid cases.
