论文摘要
我们研究了赤道平面上加速的Kerr黑洞周围旋转测试颗粒的稳定圆形轨道。为此,我们首先计算运动方程并分析粒子的参数空间。我们研究粒子自旋和黑洞的加速度对保守的角动量,旋转测试粒子的保守能量和半径对最内向稳定圆形轨道的影响。我们发现粒子旋转对轨道参数的影响几乎是线性的,黑洞加速度对这些参数的影响是非线性的。我们还探索了粒子自旋和黑洞的加速度对几乎稳定圆形轨道中旋转粒子的围绕偏移的影响。
We investigate the stable circular orbits of the spinning test particles around the accelerating Kerr black hole on the equatorial plane. To this end, we first calculate the equations of motion and analyze the parameter space for the particles. We study the effect of the particle's spin and the black hole's acceleration on the conserved angular momentum, conserved energy and radius of the spinning test particle on the innermost stable circular orbit. We find that the effect of the particle's spin on the orbit parameters is almost linear, the effect of the black hole's acceleration on those parameters is nonlinear. We also explore the effects of the particle's spin and the black hole's acceleration on the periastron shift for the spinning particle in the nearly stable circular orbit.
