Dr. Haiyang Wang has served as an Assistant Professor of Planetary Science at the University of Copenhagen, Denmark, since April 2024. Prior to this, he was a postdoctoral fellow on Exoplanets and Habitability at ETH Zurich, Switzerland, from October 2019 to March 2024. He earned his PhD in Astronomy & Astrophysics fromthe Australian National University in December 2018. Earlier in his career, heworked as an Associate Geoscientist at Baker Hughes Asia Pacific Limited in Shenzhen, China, from 2013 to 2014, upon completing his M.E. and B.E. in Geophysics at the China University of Petroleum (Huadong/Beijing). Additionally, he has been an Editor for ExoPlanetNews (a monthly electronic newsletter for latest exoplanet research) in Bern, Switzerland, since 2022.摘要:
The discovery of the first planet beyond our Solar System (i.e., exoplanet) in 1992 and the first exoplanet around a Sun-like star in 1995 revolutionized the field of exoplanetary science. To date, nearly 6000 exoplanets have been discovered and confirmed. These discoveries have reshaped our understanding of planetary diversity in the cosmos. Exoplanetary research has evolved from mere detection to comprehensive characterization, including studies of planetary interiors, atmospheres, and potential habitability.This talk will highlight crucial interplays between astrophysics, cosmochemistry, and geophysics as pathways to the next revolution in exoplanet discoveries. I will present an interdisciplinary approach to addressing fundamental questions about chemical fractionation between stars, protoplanetary disks, and rocky planets as well as within a rocky planetary body (core, mantle, and atmosphere). I will introduce novel theories, supported by cutting-edge and future stellar and exoplanetary observations, aimed at developing a quantitative framework of exoplanetology for in-depth characterization of rocky worlds.
