Biography
Liu Hui-Gen is currently an associate professor of the School of Astronomy and Space Science in Nanjing University. He is in the Space Astronomy Committee of the Chinese Space Science Society. He received his doctorate in celestial mechanics and astrometry from Nanjing University. His research focuses on the formation of exoplanets in the protoplanetary disk, the influence of open cluster environment on the formation and configuration of planetary systems, the statistical characteristics of exoplanets and the search for exoplanets with different methods, e.g. transiting, imaging. He has published more than 30 papers and participate the pre-research of many space projects, e.g. CSST, Earth 2.0, UVEyes, Miyin Projects. He also be involved in some international cooperation projects like TWINKLE and MINERVA. He has been supported by two fundings from NSFC, and participates as a scientific core member in a number of funded programs of NSFC and a key research and development project of the Ministry of Science and Technology.
Teaching
《Introduction of Planetary Atmosphere》
Brief Description:
With the increase in the number of exoplanet explorations, the characterization of exoplanets has become a hot topic in research. In particular, the detection of exoplanet atmospheres is the frontier field of exoplanet characteristics. This course takes the Earth's atmosphere as a starting point and extends to different planets in the solar system, and finally extended to the atmospheric characteristics of exoplanets. Including the background introduction of exoplanet detection, planetary atmosphere model, exoplanet atmosphere observation, and explore the habitability of planets through the characteristics of planetary atmospheres. It is hoped that after learning this course, students can understand the basic knowledge of exoplanet atmospheres, the observation methods, theoretical models, current research status, and issues to be solved. So as to lay a good foundation for further research in the direction of planetary science in the future.
