Dk. Chakraborty et Kn. Mishra, SOME GENERAL-RELATIVISTIC EFFECTS ON THE DYNAMICS OF FLUID DISKS ROTATING AROUND A SCHWARZSCHILD BLACK-HOLE, Astrophysics and space science, 226(1), 1995, pp. 79-89
In this paper we present various classes of solutions for perfect flui
d disks rotating around Schwarzschild black holes. We study the profil
es of pressure, density and specific angular momentum and the formatio
n of cusp-like structures at the inner edge of the disks. Using the tr
ial function method, we calculate the frequency of the global axi-symm
etric oscillations. We compare the results with those of the correspon
ding Newtonian calculations to find the general relativistic effects.
