Accretion onto deformed black holes via pseudo-Newtonian potentials
Anslyn J. John, Chris Z. Stevens
The Johannsen-Psaltis spacetime describes a rotating black hole with parametric deviations from the Kerr metric. By construction this spacetime explicitly violates the no-hair theo…
Bondi Accretion in the Spherically Symmetric Johannsen-Psaltis Spacetime
Anslyn John, Chris Stevens
The Johannsen-Psaltis spacetime explicitly violates the no hair theorem. It describes rotating black holes with scalar hair in the form of parametric deviations from the Kerr metri…
Black hole accretion in scalar-tensor-vector gravity
Anslyn J. John
We examine the accretion of matter onto a black hole in scalar--tensor--vector gravity (STVG) also known as modified gravity (MOG). The gravitational constant is …
Accretion onto a higher dimensional black hole
Anslyn J. John, Sushant G. Ghosh, Sunil D. Maharaj
We examine the steady-state spherically symmetric accretion of relativistic fluids, with a polytropic equation of state, onto a higher dimensional Schwarzschild black hole. The mas…
An exact isotropic solution
A. J. John, S. D. Maharaj
The condition for pressure isotropy is reduced to a recurrence equation with variable, rational coefficients of order three. We prove that this difference equation can be solved in…
