Spherical accretion of matter by charged black holes on f ( T ) $f(T)$ Gravity We studied the spherical accretion of matter by charged black holes on f ( T ) $f(T)$ Gravity. Considering the accretion model of a isentropic perfect fluid we obtain the general form of the Hamiltonian and the dynamic system for the fluid. We have analysed the movements of an isothermal fluid model with p = ω e $p=\omega e$ and where p $p$ is the pressure and e $e$ the total energy density. The analysis of the cases shows the possibility of spherical accretion of fluid by black holes, revealing new phenomena as cyclical movement inside the event horizon. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Astrophysics and Space Science Springer Journals

### Abstract

We studied the spherical accretion of matter by charged black holes on f ( T ) $f(T)$ Gravity. Considering the accretion model of a isentropic perfect fluid we obtain the general form of the Hamiltonian and the dynamic system for the fluid. We have analysed the movements of an isothermal fluid model with p = ω e $p=\omega e$ and where p $p$ is the pressure and e $e$ the total energy density. The analysis of the cases shows the possibility of spherical accretion of fluid by black holes, revealing new phenomena as cyclical movement inside the event horizon.
