论文摘要
众所周知，渐近平坦，静态和球形对称的黑洞不接受高维的爱因斯坦重力的稳定的巨大/无质量颗粒的稳定轨道。但是，对于巨大的颗粒，这种曲线理论较高的质量会发生巨大变化。我们澄清参数范围，以便在$ D $二维的Einstein-Gauss-Bonnet理论中存在稳定的绑定轨道，价格为$ 6 \ leq d \ leq 9 $。特别是，我们显示了高斯 - 河网耦合常数的下限的存在，而稳定的结合轨道不再存在。此外，我们还发现，对于理论中的广告黑孔，可以在地平线外两个稳定的圆形轨道。
As is well-known, asymptotically flat, static and spherically symmetric black holes do not admit stable bound orbits of massive/massless particles outside the horizon in higher-dimensional Einstein gravity. However, for massive particles, this dramatically changes in higher curvature theories. We clarify the parameter range such that there exist stable bound orbits in $d$-dimensional Einstein-Gauss-Bonnet theories for $6\leq d\leq 9$. In particular, we show the existence of the lower bound of the Gauss-Bonnet coupling constant below which stable bound orbits cease to exist. Moreover, we also find that for AdS-black holes in the theories, there can exist two stable circular orbits outside the horizon.
