A Possible Triple Formation Scenario of Binary Black Hole Merge With One In Pair-instability Supernova Mass Gap
Tian Huang, Xizhen Lu, Guoliang Lü +8
Observations of binary black hole (BBH) mergers detected by LIGO -- such as GW170729, GW190620, GW190706, GW230107, GW230820, and GW230928 -- feature high effective spins and prima…
Thermodynamic acceptability of spherically symmetric perfect-fluid solutions in general relativity
Dina Demissenova, Nurzada Beissen, Kuantay Boshkayev +1
Static spherically symmetric perfect-fluid solutions of Einstein's equations play a central role in relativistic astrophysics and stellar structure theory. While many exact solutio…
Formation of the Dormant Black Holes with Luminous Companions from Binary or Triple Systems
Zhuowen Li, Xizhen Lu, Guoliang Lü +6
Recently, a class of dormant black hole binaries with luminous companions (dBH-LC) has been observed, such as BH1, BH2, and BH3. Unlike previously discovered X-ray BH binari…
Wormholes in Einstein-Dirac-Maxwell theory with identical spacetime asymptotics
Vladimir Dzhunushaliev, Vladimir Folomeev, Nurzada Beissen +1
Within general relativity, we study spherically symmetric configurations with wormhole topology consisting of spinor fields and a Maxwell electric field. For such a system, we cons…
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…
Approximate perfect fluid solutions with quadrupole moment
Medeu Abishev, Farida Belissarova, Kuantay Boshkayev +4
We investigate the interior Einstein's equations in the case of a static, axially symmetric, perfect fluid source. We present a particular line element that is specially suitable f…
Some effects of nonlinear vacuum electrodynamics in strong magnetic and gravitational fields of the pulsar
Medeu Abishev, Yerlan Aimuratov, Yermek Aldabergenov +2
We consider the propagation of X-ray and gamma ray emissions in strong magnetic and gravitational fields of the pulsar in nonlinear vacuum electrodynamics. We show that the radiati…
