We review the formation and evolution of compact binary stars consisting of white dwarfs (WDs), neutron stars (NSs), and black holes (BHs). Binary NSs and BHs are thought to be the primary astrophysical sources of gravitational waves (GWs) within the frequency band of ground-based detectors, while compact binaries of WDs are important sources of GWs at lower frequencies to be covered by space interferometers (LISA). Major uncertainties in the current understanding of properties of NSs and BHs most relevant to the GW studies are discussed, including the treatment of the natal kicks which compact stellar remnants acquire during the core collapse of massive stars and the common envelope phase of binary evolution. We discuss the coalescence rates of binary NSs and BHs and prospects for their detections, the formation and evolution of binary WDs and their observational manifestations. Special attention is given to AM CVn-stars - compact binaries in which the Roche lobe is filled by another WD or a low-mass partially degenerate helium-star, as these stars are thought to be the best LISA verification binary GW sources.

紧凑双星系统的演化。

我们回顾了由白矮星(WD)、中子星(NS)和黑洞(BH)组成的致密双星的形成和演化。双星 NS 和 BH 被认为是地面探测器频段内引力波 (GW) 的主要天体物理源,而 WD 的紧凑双星则是空间干涉仪 (LISA) 覆盖的低频引力波的重要来源。 。讨论了目前对与引力波研究最相关的 NS 和 BH 性质的理解中的主要不确定性,包括如何处理致密恒星残骸在大质量恒星核心塌陷期间获得的出生踢和双星演化的共同包络阶段。我们讨论了双星 NS 和 BH 的合并速率及其检测前景、双星 WD 的形成和演化及其观测表现。特别关注 AM CVn 星 - 致密双星,其中罗氏瓣被另一个 WD 或低质量部分简并氦星填充,因为这些星被认为是最好的 LISA 验证双星引力波源。
