热亚矮星在双星演化、星震学、系外行星发现、星系演化、膨胀宇宙学中Ia型超新星前身星、引力波源这几个重要天体物理前沿研究领域中扮演着一个关键角色。然而，它们的形成机制和演化仍然不清楚。 LAMOST巡天为天文工作者开展有关热亚矮星及其相关天体研究提供了一个机遇。 基于LAMOST巡天数据我们开展三方面工作：（1）发现一批统计意义上重要的新热亚矮星样本；（2）大样本热亚矮星光谱分析和统计研究，为热亚矮星形成与演化理论提供强的观测限制；（3）搜寻具有大质量伴星的热亚矮星双星系统，发现几颗与热亚矮星相关的Ia型超新星前身星和引力波源候选体。 同时，通过本项目促进西华师范大学天文系的发展和国际合作与交流。

Hot subdwarf stars play a key role in the frontiers of astrophysical research fields, including binary evolution, asteroseismology, exoplanet findings, galaxy evolution, progenitors of type Ia supernova in expansive cosmology, gravitational wave sources and so on. However, the formation and evolution of hot subdwarfs are still unclear. LAMOST survey provides an opportunity for the astronomers to carry out the research of hot subdwarfs and related objects. Based on the survey data, we will carry out the following works: (1) finding a statistically important sample of new hot subdwarfs, (2) performing a spectroscopic analysis for the sample of hot subdwarfs and a statistic analysis to put some strong constraints on the formation and evolution theories of hot subdwarfs (3) searching for hot subdwarf binary systems with a massive companion to discover several candidates of type Ia supernovas and gravitational wave sources. Meanwhile, this program will promote the development of astronomy department of China West Normal University and the international cooperations and exchanges
