研究了一颗年轻的金牛T型星星的星周包层结构。包层气体中系统组分的超音速轨道运动导致了绕星星的弓形激波的形成。二维和三维的数值模拟表明，这些冲击的环双星信封的结构的形成中的重要作用。特别是，对于具有圆形轨道的系统，包层的未填充物质的中心区域（“间隙”）的大小基本上由弓形激波的参数决定。这些建模结果的支持所获得的估计值与观测值的差距参数的比较。
The structure of a circumstellar envelope around a young binary T Tauri star is considered. The supersonic orbital motion of the system components in the envelope gas leads to the formation of bow shocks around the star. Two- and three-dimensional numerical modeling indicates an important role of these shocks in the formation of the structure of the circumbinary envelope. In particular, for systems with circular orbits, the size of the central region of the envelope that is not filled with matter (the “gap”) is essentially determined by the parameters of the bow shocks. These modeling results are supported by comparisons of the obtained estimates for the gap parameters with observations.
