论文摘要
我们提供了$ f（r）$重力中静态球形对称黑洞的薄积盘的描述。在这方面，我们首先研究了$ f（r）$重力中的黑洞的视野。还计算了运动方程和有效电位的方程式，最终导致可能存在积聚盘的最内向轨道。我们得出在圆形轨道上移动的颗粒的特定能量，特定的角动量和角速度。还提出了各种参数的比较研究。还指出了事件范围，宇宙学范围，最内向和最外面稳定的圆形轨道的位置。
We provide a description of a thin accretion disc for a static spherically symmetric black holes in $f(R)$ gravity. In this regard, we first study the horizons of black holes in $f(R)$ gravity. The equation of motion and effective potential are also computed which eventually leads to possible existence of innermost circular orbits of accretion disc. We derive the specific energy, specific angular momentum and angular velocity of the particles moving in circular orbits also. A comparative study of various parameters are also presented. The locations of the event horizon, cosmological horizon, innermost and outermost stable circular orbits are also pointed out.
