主持人：李文雄
嘉宾介绍：Prof. lair (pronounced "ya-eer") Arcavi is an associate professor at Tel Aviv University and the director of the George S.Wise Observatory. He obtained his PhD at the Weizmann Institute in 2013, and continued to a post-doc position at LasCumbres Obseryatory and UC Santa Barbara., partly as a NASA Einstein Fellow. He joined Tel Aviv University as faculty in 2018. His research focuses on rapid response observations of core-collapse supernovae, rapidly evolving transients. tidal disruption events and kilonovae, and on continuous global observations for asteroseismology of massive stars
主要内容：Supernovae, tidal disruption events and merging neutron stars can provide a wealth of physical insights from nuclear physics to cosmology; they can teach us about the creation of the elements, the formation of compact objects, accretion processes, feedback, galaxy evolution, and more. l will present how my research group is investigating the nature of tidal disruption events. their surprising eission properties, and how wide-field X-ray observations can help solve some of the puzzles in this field. l will also briefly review how we are using supernovae to constrain late-stage stellar evolution and explosion, and asteroseismology to constrain the inner structure of massive stars, and how we are hoping to find more gravitational-wave counterparts through multi-observatory coordination.
