Rotating Hot White Dwarfs
Kuantay Boshkayev, Jorge A. Rueda, Bakytzhan Zhami
We consider the effects of rotation and temperature on the structure of white dwarfs in order to compare them with the estimated data from observations.
A perfect-fluid spacetime for a slightly deformed mass
Medeu Abishev, Kuantay Boshkayev, Hernando Quevedo +1
We present approximate exterior and interior solutions of Einstein's equations which describe the gravitational field of a static deformed mass distribution. The deformation of the…
Accretion disks around a mass with quadrupole
Medeu Abishev, Kuantay Boshkayev, Hernando Quevedo +1
We consider the stability properties of test particles moving along circular orbits around a mass with quadrupole. We show that the quadrupole modifies drastically the properties o…
Equilibrium structure of white dwarfs at finite temperatures
Kuantay Boshkayev, Jorge A. Rueda, Bakytzhan Zhami +2
Recently, it has been shown by S.~M. de Carvalho et al. (2014) that the deviations between the degenerate case and observations were already evident for 0.7-0.8 M white d…
Geodesics in the field of a rotating deformed gravitational source
Kuantay Boshkayev, Hernando Quevedo, Marzhan Abutalip +2
We investigate equatorial geodesics in the gravitational field of a rotating and deformed source described by the approximate Hartle-Thorne metric. In the case of massive particles…
On the equivalence of approximate stationary axially symmetric solutions of Einstein field equations
Kuantay Boshkayev, Hernando Quevedo, Saken Toktarbay +2
We study stationary axially symmetric solutions of the Einstein vacuum field equations that can be used to describe the gravitational field of astrophysical compact objects in the…
