主序后相接双星的研究
发布时间:2021-07-02 07:42
主序后相接双星特指一类由演化脱离了主序带的恒星所组成的相接系统,因此要求至少有一颗子星演化至主序后阶段。在观测上,主序后相接双星应该具有较低的金属丰度[Fe/H]以及较小的表面引力加速度log(g)。相较于一般主序阶段的相接系统,在相接阶段早期(相接早期—大质量比端)形成的主序后相接双星由于子星自身极端的不稳定性(偏离热动平衡),可能会更快地演化至极短周期、深度相接阶段。并且,主序阶段占据了恒星一生中绝大部分寿命,主序后相接双星的形成可能意味着相接系统的演化临近终点—接近并合。因此,在相接阶段晚期(相接晚期—小质量比端)形成的主序后相接双星可以作为并合单星的前身星看待,从而为相接双星的并合模型提供一定的观测参考。本文首先从一般的相接双星出发,介绍了相接双星的研究历史以及研究现状,并借此引入主序后相接双星的研究意义;然后进入到观测研究部分,介绍了主序后相接双星可能的观测特征,以及对一颗主序后候选体LINEAR 199576的测光解轨情况。最后深入到理论研究部分,对主序后相接双星的周期变化以及非热平衡状态展开讨论。具体研究成果如下:1.根据主序后可能的观测特征,指出LINEAR 19957...
