我们系统研究了在f(R,T)引力耦合欧拉-海森堡非线性电动力学中，小致密天体绕磁带电黑洞运行的“ zoom-whirl”周期轨道。评估了磁荷Q_m和欧拉-海森堡参数a对最内稳定圆轨道（ISCO）和边缘束缚轨道（MBO）特性的影响，尤其聚焦于进动参数q，系统考察磁荷及其他参数对周期轨道轨迹的影响。利用数值kludge方法生成这些周期轨道的引力波波形。研究结果表明，磁荷不仅能显著改变进动参数，还能改变周期轨道的轨迹；此外，改变磁荷Q_m会使引力波波形产生显著相位偏移，而其他参数对引力波的影响相对较弱。
英文摘要
We systematically investigate the zoom-whirl periodic orbits of a small compact object orbiting a magnetically charged black hole in $f(R, T)$ gravity coupled with Euler-Heisenberg nonlinear electrodynamics. We evaluate the impact of the magnetic charge $Q_m$ and the Euler-Heisenberg parameter $a$ on the characteristics of the innermost stable circular orbit (ISCO) and the marginally bound orbit (MBO). Particularly, we focus on the precession parameter q and systematically examine how the magnetic charge and other parameters affect the trajectories of periodic orbits. Using the numerical kludge method, we generate gravitational waveforms for these periodic orbits. The results presented in our work demonstrate that the magnetic charge can significantly modify not only the precession parameter but also the orbital trajectories of the periodic orbits. Moreover, changing the magnetic charge $Q_m$ could cause a significant phase shift in the gravitational waveforms, while other parameters exert a relatively weaker influence on the gravitational waves.
