摘要：
We discuss results of 2D and 3D numerical simulations of gas accretion processes in binary stars of the T Tau type. Analysis of the obtained flow structure shows that in such systems following gas dynamic details are formed: inner gap, circumstellar disks, bow shocks before components, and gaseous "bridge" between the components. It is shown that the bow shocks govern the shape and size of the inner gap. We also analyze matter flows inside the gap and redistribution of the accreted matter among the components.
