Geometric properties versus particle motion in the Fan-Wang spacetime
Gulnara Suliyeva, Kuantay Boshkayev, Talgar Konysbayev +7
In this work, we explore general relativistic effects and geometric properties of the Fan-Wang spacetime, one of the simplest regular solutions that can be obtained in nonlinear el…

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)…
