Numerical analysis of quasi-periodic oscillations with spherical spacetimes
Kuantay Boshkayev, Orlando Luongo, Marco Muccino
We numerically test quasi-periodic oscillations using three theoretically-motivated models of spacetime adopting neutron star sources. Then, we compare our findings with a spherica…
Numerical analyses of M31 dark matter profiles
Kuantay Boshkayev, Talgar Konysbayev, Yergali Kurmanov +4
We reproduce the rotation curve of the Andromeda galaxy (M31) by taking into account its bulge, disk, and halo components, considering the last one to contain the major part of dar…
Adiabatic theory in Kerr spacetimes
Kuantay Boshkayev, Gulmira Nurbakyt, Hernando Quevedo +7
We present the main aspects of the adiabatic theory and show that it can be used to study the motion of test particles in general relativity. The theory is based upon the use of ve…
Adiabatic theory of motion of bodies in the Hartle-Thorne spacetime
Gulnara Sulieva, Kuantay Boshkayev, Gulmira Nurbakyt +5
We study the motion of test particles in the gravitational field of a rotating and deformed object within the framework of the adiabatic theory. For this purpose, the Hartle-Thorne…
Accretion disk luminosity for black holes surrounded by dark matter with tangential pressure
Kuantay Boshkayev, Talgar Konysbayev, Yergali Kurmanov +2
We study the motion of test particles in the gravitational field of a Schwarzschild black hole surrounded by a spherical dark matter cloud with non-zero tangential pressure and com…
