Hayward时空中测试磁场的结构和带电粒子的运动

Structure of test magnetic fields and charged particle motion around the Hayward spacetime

Ziou Yang, Yen-Kheng Lim

摘要:

以海沃德度规为背景,通过求解麦克斯韦方程,得到了海沃德时空中测试磁场的位形。磁场线在规则的海沃德内部呈现偶极环状结构,在远离圆柱轴处趋于渐近均匀结构。然后在这个时空中研究带电粒子的运动。研究了赤道平面上圆轨道的参数和稳定性。非赤道运动方面也进行了研究。

英文摘要:

A configuration of a test magnetic field in Hayward spacetime is obtained by solving Maxwell's equation with the Hayward metric as the background. The magnetic field lines show a dipole loop-like configuration in the regular Hayward interior, and tends to an asymptotically uniform structure away from the cylindrical axis. The motion of charged particles is then studied in this spacetime. The parameters and stability of circular orbits on the equatorial plane are studied. Aspects of non-equatorial motion are also studied.
