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.

近距离双星的演化可以产生单星中没有的物体和现象。发出低质量X射线的双星和共生星就属于这一类，但这些相对罕见的天体的进化起源尚不确定。这项研究将通过构建恒星种群模型来探索这些天体的可能起源，使它们能够在不同的场景下进化。将进化的模型种群与观察到的种群进行比较，可能有助于揭示这些系统形成的确切机制。
