标题： Spherical Accretion of Matter by Charged Black Holes on f(T) Gravity

摘要： 我们研究了带电黑洞对物质的球对称吸积问题$f(T)$。 考虑一种等熵完美流体的吸积模型，我们得到了流体的哈密顿量和动力学系统的通解形式。 我们分析了一个等温流体模型的运动情况，其中$p=\omega e$表示压力$p$，$e$表示总能量密度。 这些情况的分析表明流体可以通过黑洞实现球对称吸积，并揭示了事件视界内出现周期性运动的新现象。 显示英文摘要

摘要： We studied the spherical accretion of matter by charged black holes on $f(T)$ 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 $p=\omega e$ and where $p$ is the pressure and $e$ 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.
