Accretion disk luminosity around rotating naked singularities
Yergali Kurmanov, Kuantay Boshkayev, Talgar Konysbayev +6
We explore circular geodesics of neutral test particles in the gravitational field of a rotating deformed mass. The geometry around this source is described by the Quevedo-Mashhoon…

Gravitational capture cross-section in Zipoy-Voorhees spacetimes
Serzhan Momynov, Kuantay Boshkayev, Hernando Quevedo +5
We consider geodesics of massive and massless test particles in the gravitational field of a static and axisymmetric compact object described by the quadrupolar metric (-metric)…

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…
