论文摘要
我们研究了Schwarzschild空间的持续painlevé-Gullstrand时间的叶子中包含的开放式和闭合的轴对称边缘外部捕获的表面。我们确定了一个以任意数量的自我交流为特征的黑洞内部中的封闭MOT家族。这表明[Phys.Rev.D 100，084044（2019）]中报告的自我截距行为可能比预期的要多得多。我们还考虑开放的表面，发现它们的行为受到高度限制，但包括地平线内有多个自身交流的表面。我们认为，开放MOT的行为识别并限制了极端比率合并期间MOT的局部行为。
We study the open and closed axisymmetric marginally outer trapped surfaces contained in leaves of constant Painlevé-Gullstrand time for Schwarzschild spacetimes. We identify a family of closed MOTS in the black hole interior characterized by an arbitrary number of self-intersections. This suggests that the self-intersecting behaviour reported in [Phys.Rev.D 100, 084044 (2019)] may be a far more generic phenomenon than expected. We also consider open surfaces, finding that their behaviour is highly constrained but includes surfaces with multiple self-intersections inside the horizon. We argue that the behaviour of open MOTS identifies and constrains the possible local behaviour of MOTS during extreme mass ratio mergers.
