Shirokov and Shapiro Effects in the Hartle-Thorne Spacetime
Anuar Idrissov, Kuantay Boshkayev, Serzhan Momynov +4
We investigate the influence of rotation and quadrupole deformations of astrophysical compact objects on the Shirokov and Shapiro effects within the Hartle-Thorne spacetime, which…
Shadow, Emission, and Strong-Field Lensing of Dilatonic Black Holes
Kuantay Boshkayev, Ainur Urazalina, Aidana Kurmanbek +2
We study the shadow and strong-field optical properties of a static, spherically symmetric dyon-like dilatonic black hole. The photon sphere radius, critical impact parameter, and…
Constraining quadrupole deformations with relativistic effects
Daniya Utepova, Kuantay Boshkayev, Serzhan Momynov +4
We investigate two general relativistic effects - namely, the Shirokov and Shapiro effects - within the framework of the Zipoy-Voorhees spacetime (-metric), which generalizes th…
Geodesic deviation in the -metric
Anuar Idrissov, Kuantay Boshkayev, Konstantinos F. Dialektopoulos +2
We consider the tidal forces between test particles falling along geodesics in the exterior spacetime generated by a static and axially symmetric compact matter source with non-van…
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)…
