Late Stages of Close Binary Evolution

距离很近的双星的演化可以产生在单星中找不到的天体和现象。发射低质量x射线的双星和共生星属于这一类，但这些相对罕见的天体的进化起源是不确定的。这项研究将通过构建模型恒星群来探索这些物体的可能起源，允许它们在不同的情况下进化。将进化的模型种群与观察到的种群进行比较，可能有助于阐明这些系统形成的精确机制。

The evolution of closely separated binary stars can produce objects and phenomena not found among single stars. Low-mass X-ray emitting binary stars and symbiotic stars fall into this category, but the evolutionary origins of these comparatively rare objects are uncertain. This research will explore possible origins of these objects by constructing model stellar populations, allowing them to evolve under different scenarios. A comparison of the evolved model populations with observed populations may shed light on the precise mechanisms responsible for the formation of these systems.
