标题： Magnetized Particle Motion Around Black Hole in Braneworld

摘要： 我们研究了磁化粒子在布兰世界中的黑洞周围轨道运动，该布兰世界置于渐近均匀磁场中。 利用哈密顿-雅可比形式主义，研究了膜参数对磁化自旋粒子径向运动有效势的影响。 发现光子和缓慢移动粒子的圆轨道可能在$r = 3M$附近变得稳定。 有人认为，最内侧稳定圆轨道的半径对膜参数的变化非常敏感。 de Felice 等人在参考文献\refcite{rs99,98}中考虑了不带 Weil 参数的类似讨论。 显示英文摘要

摘要： We investigate the motion of a magnetized particle orbiting around a black hole in braneworld placed in asymptotically uniform magnetic field. The influence of brane parameter on effective potential of the radial motion of magnetized spinning particle around the braneworld black hole using Hamilton-Jacobi formalism is studied. It is found that circular orbits for photons and slowly moving particles may become stable near $r = 3M$. It was argued that the radii of the innermost stable circular orbits are sensitive on the change of brane parameter. Similar discussion without Weil parameter has been considered by de Felice et all in Ref. \refcite{rs99,98}.
