论文摘要
我们使用三维模拟与耦合的流体动力学和蒙特卡洛辐射转移，以表明损坏的圆盘内盘施放的阴影在外盘上的位置角度的狭窄范围内移动。随着时间的流逝，随着内部的圆盘进攻，阴影似乎在方位角来回摇摆。效果之所以发生，是因为内盘围绕矢量围绕不是外盘的角动量向量。我们将发现与圆盘中阴影的最新观察联系起来。
We use three dimensional simulations with coupled hydrodynamics and Monte Carlo radiative transfer to show that shadows cast by the inner disc in broken circumbinary discs move within a confined range of position angles on the outer disc. Over time, shadows appear to rock back and forth in azimuth as the inner disc precesses. The effect occurs because the inner disc precesses around a vector that is not the angular momentum vector of the outer disc. We relate our findings to recent observations of shadows in discs.
