More on gravitational waves from double monodromy inflation
Medeu Abishev, Aigerim Abylayeva, Andrea Addazi +2
We further analyze phenomenological implications of double axion monodromy inflation proposed in Ref. Phys. Rev. D 104, L081302 (2021), in gravitational wave physics. We show that…
Gravitational field of slightly deformed naked singularities
Saken Toktarbay, Hernando Quevedo, Medeu Abishev +1
We derive a particular approximate solution of Einstein equations, describing the gravitational field of a mass distribution that slightly deviates from spherical symmetry. The dev…
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…
Orbital stability of the restricted three body problem in General Relativity
M. Abishev, H. Quevedo, S. Toktarbay +1
We consider the problem of orbital stability of the motion of a test particle in the restricted three-body problem, by using the orbital moment and its time derivative. We show tha…
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…
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…
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…
