我们提供了一套完整的整体解决方案的粘性跨音速流（VTF）周围的黑洞和中子星。这些解描述了从黑洞视界或从中子星星表面到流与开普勒盘结合处的光学厚流和光学薄流。我们研究的性质的多个音速点的平流，旋转，粘度，加热和冷却的功能。稳定的冲击波，加入两个跨音速的解决方案，被发现存在于一个大的区域的参数空间。我们根据流动是否有驻激波来对解进行分类。我们没有发现新的拓扑结构的解决方案以外的观察到在我们以前的研究等温VTF。我们特别强调边界条件的重要性，并认为我们有最完整的解决方案的吸积和风周围的黑洞和中子星。
We provide the complete set of global solutions of viscous transonic flows (VTFs) around black holes and neutron stars. These solutions describe the optically thick and optically thin flows from the horizon of the black hole or from the neutron star surface to the location where the flow joins with a Keplerian disk. We study the nature of the multiple sonic points as functions of advection, rotation, viscosity, heating and cooling. Stable shock waves, which join two transonic solutions, are found to be present in a large region of the parameter space. We classify the solutions in terms of whether or not the flow can have a standing shock wave. We find no new topology of solutions other than what are observed in our previous studies of isothermal VTFs. We particularly stress the importance of the boundary conditions and argue that we have the most complete solution of accretion and winds around black holes and neutron stars.
