环双星盘系统中的间隙有多亮？
How bright are the gaps in circumbinary disk systems?
摘要：
当一个环双星盘包围着一个质量至少是主星质量$\sim 10^{-2}\times$的双星时，盘上就会形成一个半径是双星间距几倍的几乎为空的空腔。狭窄的物质流从环双星盘的内缘进入双星本身的区域，在那里它们最终加入到围绕双星成员旋转的小圆盘上。使用数据从3-D MHD模拟这个过程中，我们确定这些流的光度，这主要是由于弱层流冲击，一般只有百分之几的光度相邻地区的无论是环双星磁盘或“迷你磁盘”。因此，这种亮度几乎不影响在一个完美的黑暗的间隙区域的基础上预测的热连续的赤字。
英文摘要：
When a circumbinary disk surrounds a binary whose secondary's mass is at least $\sim 10^{-2}\times$ the primary's mass, a nearly empty cavity with radius a few times the binary separation is carved out of the disk. Narrow streams of material pass from the inner edge of the circumbinary disk into the domain of the binary itself, where they eventually join onto the small disks orbiting the members of the binary. Using data from 3-d MHD simulations of this process, we determine the luminosity of these streams; it is mostly due to weak laminar shocks, and is in general only a few percent of the luminosity of adjacent regions of either the circumbinary disk or the "mini-disks". This luminosity therefore hardly affects the deficit in the thermal continuum predicted on the basis of a perfectly dark gap region.
