What can we extract from quasi-periodic oscillations?
Kuantay Boshkayev, Donato Bini, Jorge Rueda +3
In light of the relativistic precession model, we present here detailed analyses, extending the ones performed in the Schwarzschild and Kerr spacetimes. We consider the kilohertz q…
Particles under radiation thrust in Schwarzschild space-time from a flux perpendicular to the equatorial plane
Donato Bini, Andrea Geralico, Robert T. Jantzen +1
Motivated by the picture of a thin accretion disc around a black hole, radiating mainly in the direction perpendicular to its plane, we study the motion of test particles interacti…
Effect of an arbitrary spin orientation on the quadrupolar structure of an extended body in a Schwarzschild spacetime
Donato Bini, Andrea Geralico
The influence of an arbitrary spin orientation on the quadrupolar structure of an extended body moving in a Schwarzschild spacetime is investigated. The body dynamics is described…
Radiation drag in the field of a non-spherical source
Donato Bini, Andrea Geralico, Andrea Passamonti
The motion of a test particle in the gravitational field of a non-spherical source endowed with both mass and mass quadrupole moment is investigated when a test radiation field is…
Refraction index analysis of light propagation in a colliding gravitational wave spacetime
Donato Bini, Andrea Geralico, Maria Haney
The optical medium analogy of a given spacetime was developed decades ago and has since then been widely applied to different gravitational contexts. Here we consider the case of a…
Observer-dependent optical properties of stationary axisymmetric spacetimes
Donato Bini, Fernando de Felice, Andrea Geralico
The world lines of null particles admit arbitrary parametrizations. In the presence of a family of observers one may introduce along a null world line an extension of the so-called…
