1301.4633 (A. M. Al Zahrani et al.)

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

A. M. Al Zahrani, Valeri P. Frolov, Andrey A. Shoom
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 in?finity. 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.
