利用三维光滑粒子流体动力学模拟方法研究了相互作用双星中来自拉格朗日内点的气流与吸积盘的碰撞。我们发现，流材料的一个显着的部分可以跳弹盘边缘和溢出朝向较小的半径，这产生了显着的非轴对称结构的吸收柱朝向中心对象。我们讨论的影响，我们的结果的观测和时间依赖的模型的低质量X射线双星，激变变量和超软X射线源。
We investigate the impact between the gas stream from the inner Lagrangian point and the accretion disk in interacting binaries, using three dimensional Smooth Particle Hydrodynamics simulations. We find that a significant fraction of the stream material can ricochet off the disk edge and overflow towards smaller radii, and that this generates pronounced non-axisymmetric structure in the absorption column towards the central object. We discuss the implications of our results for observations and time-dependent models of low-mass X-ray binaries, cataclysmic variables and supersoft X-ray sources.
