Personal introduction Biography

Dr. Liu Hui-Gen is currently an associate professor of the School of Astronomy and Space Science in Nanjing University. I serve as a Committee Member of the Division of Space Astronomy, Chinese Society for Space Research; a Youth Committee Member of the Space Science and Experimentation Division, Chinese Society of Astronautics; and a Young Editorial Board Member of the Journal of Space Science and Experimentation. is also recognized as a Science Communication Expert by the Jiangsu Association for Science and Technology. The primary research interests include planetary systems in star clusters, statistical properties of exoplanets, detection of habitable-zone planets, and characterization of exoplanetary atmospheres. I contribute to the development of the Time-domain Observatory (TiDO) at Nanjing University and have participated in pre-research studies for key Chinese space projects, including the China Space Station Telescope (CSST), Earth 2.0, and the MEAYIN program. Internationally, I collaborate on projects such as TWINKLE and MINERVA. Currently, I serve as Deputy Director of the MEAYIN Science Center and leads scientific operations for the Time-domain Observatory (TiDO). I have authored or co-authored over 40 peer-reviewed publications in prestigious journals including The Innovation and Nature Astronomy. My researches have been supported by multiple competitive grants, including National Key R&D Program, General and Young Scientists Programs of the National Natural Science Foundation of China (NSFC), and the Jiangsu Provincial Natural Science Foundation for Young Scholars.

《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.
