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…
Newtonian Shirokov Effect: Epicyclic Frequency Splitting from Mass Multipoles
Anuar Idrissov, Kuantay Boshkayev, Abylaikhan Tlemissov +1
We analyze small oscillations of nearly circular orbits in an axisymmetric Newtonian potential expanded in mass multipoles, as the classical counterpart of the relativistic Shiroko…
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…
