Magnetized relativistic accretion disk around a spinning, electrically charged, accelerating black hole: Case of the C metric

Autor: Shokoufe Faraji, Audrey Trova, Vladimir Karas

Publikováno v: Physical Review D. 105

This paper examines the general relativistic model of a geometrically thick configuration of an accretion disc around an electrically charged black hole in an accelerated motion, as described by the C-metric family. We aim to study the effects of the

Magnetized tori in the background of a deformed compact object

Autor: Audrey Trova, S. Faraji

The aim of this work is to study the relativistic accretion thick disc model raised by a deformed compact object that slightly deviated from spherical up to the quadrupole moment by utilising the q-metric. This metric is the simplest asymptotically f

We perform a bivariate Taylor expansion of the axisymmetric Green function in order to determine the exterior potential of a static thin toroidal shell having a circular section, as given by the Laplace equation. This expansion, performed at the cent

This work explores the dynamic properties of test particles surrounding a distorted, deformed compact object. The astrophysical motivation was to choose such a background as to constitute a more reasonable model of a real situation that arises in the
