标题： Eclipsing Light-Curve Asymmetry for Black-Hole Accretion Flows

摘要： 我们提出了一种用于黑洞吸积流的掩食光变诊断方法。 当黑洞内吸积盘的辐射被伴星遮挡时，观测到的光变曲线在0.1至1秒的时间尺度上，在掩食进入和退出阶段变得不对称。 这种光变曲线分析提供了一种验证吸积流相对论性质的方法，基于黑洞的特殊/广义相对论效应。 对于薄盘掩食光变曲线的“偏斜度”为$\sim 0.08$，而对胖盘则为$\sim 0$，因为最内层区域被盘外缘自身遮挡。 显示英文摘要

摘要： We propose an eclipsing light-curve diagnosis for black-hole accretion flows. When emission from an inner accretion disk around a black hole is occulted by a companion star, the observed light curve becomes asymmetric at ingress and egress on a time scale of 0.1-1 seconds. This light-curve analysis provides a means of verifying the relativistic properties of the accretion flow, based on the special/general relativistic effects of black holes. The ``skewness'' for the eclipsing light curve of a thin disk is $\sim 0.08$, whereas that of a slim disk is $\sim 0$, since the innermost part is self-occulted by the disk's outer rim.
