吴程远博士目前是中国科学院云南天文台副研究员。2019年博士毕业于中国科学院云南天文台，随后于清华大学物理系担任博士后工作。2022年于云南天文台担任助理研究员，2024年起任副研究员。他主要研究方向包括吸积白矮星演化、双白矮星并合演化以及核塌缩超新星光变模拟。White dwarfs (WDs) are the most common evolutionary fate of less massive single stars. It is estimated that there are about 1010 WDs in our galaxy, of which 2.5 × 108 reside in binaries consisting of two WDs, and about half of these binary WDs are close enough to begin mass transfer within a Hubble time. Double WD mergers play key role in astrophysics. They are important gravitational wave sources and are related to many objects, such as Type Ia supernovae, neutron stars, hot subdwarfs, etc. The theoretical understanding of the evolution of WD merger remnants is based on using information from threedimensional (3D) postmerger configurations to build onedimensional (1D) models whose further evolution is computed in detail through their longer-duration phases. In this talk, I’ll first introduce double WD binaries, including their formation channels, importance in astrophysics, then I’ll introduce our simulations on the post-merger evolution of double WD merger remnants and discuss the related objects.
