论文摘要
理解宇宙的起源和演变的方法之一是知道星系如何形成和进化。在这方面，恒星形成史（SFH）的研究在准确理解星系中起着重要作用。在本文中，我们使用了长周期变量恒星（LPV）来估计仙女座星系中的SFH（M31）。这些凉爽的恒星在进化的最后阶段达到了峰值光度。他们的出生质量与它们的发光直接相关。因此，我们使用恒星演化模型构建质量函数和恒星形成历史。
One of the ways to understand the genesis and evolution of the universe is to know how galaxies have formed and evolved. In this regard, the study of star formation history (SFH) plays an important role in the accurate understanding of galaxies. In this paper, we used long-period variable stars (LPVs) to estimate the SFH in the Andromeda galaxy (M31). These cool stars reach their peak luminosity in the final stage of their evolution; their birth mass is directly related to their luminosity. Therefore, we construct the mass function and the star formation history using stellar evolution models.
