摘要:

本文在$f(T)$遥平行引力场的背景下研究了黑洞附近流体的吸积过程。具体地说,通过由哈密顿系统进行动力学分析,我们能够找到音速点。之后,我们考虑了不同的等温测试流体,以研究它们落在黑洞上时的吸积过程。我们发现这些流可以根据状态方程和黑洞的特征进行分类。比较了$f(T)$和$f(R)$重力的结果。

英文摘要:

In this paper, we study the accretion process for fluids flowing near a black hole in the context of $f(T)$ teleparallel gravity. Specifically, by performing a dynamical analysis by a Hamiltonian system, we are able to find the sonic points. After that, we consider different isothermal test fluids in order to study the accretion process when they are falling onto the black hole. We found that these flows can be classified according to the equation of state and the black hole features. Results are compared in $f(T)$ and $f(R)$ gravity.
