标题： Theory of thermal and ionization effects in colliding winds of WR+O binaries

摘要： WR+O双星系统的风碰撞相互作用区是一个高度复杂的环境。 在这篇综述中，我们总结了过去几年在理解这一现象理论方面的进展。 我们回顾了不同物理过程对该相互作用区的影响，其中包括几何形状和轨道运动、辐射力、热传导、不稳定性与湍流、电离辐射、尘埃形成、团块状风、磁场以及粒子加速。 讨论了这些影响对观测的启示。 随后，我们转向这些过程之间相互作用的重要问题。 由于涉及众多物理过程，数值模拟通常是必不可少的。 最后，我们探讨了这些过程在WR+O双星系统风碰撞相互作用区的热性质和电离性质中的共同作用。 显示英文摘要

摘要： The colliding winds interaction zone in WR+O binaries is a highly complex environment. In this review we summarize the progress made towards its theoretical understanding during the last years. We review the effect of different physical processes on the interaction zone, among them geometry and orbital motion, radiative forces, thermal conduction, instabilities and turbulence, ionizing radiation, dust formation, clumped winds, magnetic fields, and particle acceleration. Implications with regard to observations are discussed. Subsequently, we proceed to the important question of mutual interaction amongst these processes. Because of the wealth of physical processes involved, numerical simulations are usually mandatory. Finally, we turn to the combined role these processes play for the thermal and ionization properties of the colliding winds interaction zone in WR+O binaries.
