带电粒子绕弱磁化Schwarzschild黑洞运动的临界逃逸速度

Critical escape velocity for a charged particle moving around a weakly magnetized Schwarzschild black hole

A. M. Al Zahrani, Valeri P. Frolov, Andrey A. Shoom

摘要:

讨论了带电粒子在弱磁化静态非旋转黑洞时空中的运动。研究了在什么条件下,一个原本以圆形轨道围绕黑洞旋转的带电粒子,被另一个粒子或光子踢飞后,可以逃逸到无穷远。我们确定了处于最内层稳定圆轨道的粒子的逃逸速度,并讨论了以近临界速度运动的粒子的性质。我们表明,在一般情况下,这样的运动是混沌的。

英文摘要:

We discuss charged particles motion in a spacetime of a weakly magnetized static non-rotating black hole. We study under which conditions a charged particle originally revolving around the black hole at a circular orbit after being kicked by another particle or photon can escape to infinity. We determine the escape velocity for particles at the innermost stable circular orbits and discuss the properties of particles moving with near-critical velocity. We show that in a general case such a motion is chaotic.
