本轮频率通常在X射线双星中被观测到，是探测致密天体周围强引力场的有力天体物理手段。我们研究了一般稳态轴对称虫洞周围赤道面内的本轮频率。我们首先探究虫洞的存在性，将其与克尔黑洞（Kerr black hole）区分开来。一旦获得虫洞的观测数据，我们提出了一种重构相关度规的策略。最后，我们讨论了该方法的意义并展望了未来可能的研究方向。
英文摘要：
Epicyclic frequencies are usually observed in X-ray binaries and constitute a powerful astrophysical mean to probe the strong gravitational field around a compact object. We consider them in the equatorial plane around a general stationary and axially symmetric wormhole. We first search for the wormholes' existence, distinguishing them from a Kerr black hole. Once there will be available observational data on wormholes, we present a strategy to reconstruct the related metrics. Finally, we discuss the implications of our approach and outline possible future perspectives.
Quasi-harmonic oscillations of charged particles in static axially symmetric space-times immersed in a uniform magnetic field
在我们以前的研究[Phys. Rev. D 99（2019）4，044012]的继续中，我们研究了带电粒子在$γ$ -度规中的运动。我们提供了一些例子，在赤道平面内的卷曲轨迹和逃逸轨迹外的赤道平面。最后，我们考虑了由于赤道平面上稳定圆轨道的小位移引起的谐波振荡，并计算了不同形变参数和磁场值下的周转频率。
