【摘要】：正大熊W型相接双星是两颗子星均充满并溢出各自洛希瓣、具有对流公共包层的双星系统.相接双星中存在各种各样的相互作用,给理论模型带来许多可变参量,对理论研究提出了挑战.上世纪六七十年代,经过激烈的争论,相接双星的对流公共包层模型得到公认,相接双星的热弛豫震荡模型、相接不连续模型及角动量损失理论相继被提出.然而,在过去的近40 yr中,理论研究似乎遇到了瓶颈.大量未知参量的共存,使相接双星的理论研究难以进一步开展.研究相接双星的聚星、星团环境,能为相接双星的形成和演化提供丰富的信息,因而是探索相接双星演化问题潜在的生长点.越来越多的观测证据表明,大量相接双星存在于聚星系统或者星团当中.作为母系统的聚星、星团为研究其中的相接双
[Abstract]:The W-junction binary star is a binary system in which both substars are filled and overflow their Losch lobes with convective common cladding. There are various interactions in the intersecting binary stars, which bring many variable parameters to the theoretical model and challenge the theoretical research. In the sixties and seventies of the last century, the convection common cladding model of the binary stars was recognized, and the thermal relaxation oscillation model, the discontinuous model and the theory of angular momentum loss were put forward one after another. However, in the past nearly 40 yr, theoretical research seems to meet a bottleneck. Due to the coexistence of a large number of unknown parameters, it is difficult to further develop the theoretical study of binary stars. The study of the cluster environment can provide abundant information for the formation and evolution of the binary stars, so it is a potential growth point to explore the evolution of the interlocking binary stars. A growing body of observational evidence suggests that a large number of conjunctive binary stars are present in the system or cluster. As the parent system of the star cluster, the cluster for the study of the junction of the two
