回顾了由白矮星(WDS)、中子星(NSS)和黑洞(BHS)组成的致密双星的形成和演化。致密恒星双星的合并有望成为即将到来的引力波(GW)天文学的最重要来源。在综述的第一部分，我们讨论了具有NS和/或BH分量的紧密双星的观测表现及其合并率，双星系致密恒星形成和演化中的关键问题，包括NSS和BHS在大质量恒星核心塌缩时获得的诞生踢点的处理，以及与NS-NS、NS-BH和BH-BH双星合并率最相关的双星演化的共同包络阶段。综述的第二部分主要讨论了双星WD的形成和演化及其观测表现，包括它们作为具有重要宇宙学意义的热核SNIa的前身所起的作用。我们还考虑了AM CVn-STAR，它们被认为是未来低频GW空间干涉仪最好的验证双星。
We review the formation and evolution of compact binary stars consisting of white dwarfs (WDs), neutron stars (NSs), and black holes (BHs). Mergings of compact-star binaries are expected to be the most important sources for forthcoming gravitational-wave (GW) astronomy. In the first part of the review, we discuss observational manifestations of close binaries with NS and/or BH components and their merger rate, crucial points in the formation and evolution of compact stars in binary systems, including the treatment of the natal kicks, which NSs and BHs acquire during the core collapse of massive stars and the common envelope phase of binary evolution, which are most relevant to the merging rates of NS-NS, NS-BH and BH-BH binaries. The second part of the review is devoted mainly to the formation and evolution of binary WDs and their observational manifestations, including their role as progenitors of cosmologically-important thermonuclear SN Ia. We also consider AM CVn-stars, which are thought to be the best verification binary GW sources for future low-frequency GW space interferometers.
