Description

Title: Exoplanetary atmospheres: motivations, detection, and theories
Speaker:Xianyu Tan (谭先瑜)
 
Abstract: Exoplanet is an emerging and rapidly growing field with joint efforts from astronomy, planetary sciences, atmospheric sciences, physics, biology, and so on. Characterization of exoplanetary atmospheres is among the forefronts in exoplanetary sciences, concerning fundamental questions such as how diverse planets are, how planets form and evolve, and how do we detect life outside the solar system. This talk will be firstly dedicated to laying out the current progress in the field of exoplanetary atmospheres by introducing typical observations, theoretical modeling efforts, and a few interesting examples. Some of my own work in relevant contexts will also be presented.  
 
Bio:
Xianyu Tan is currently a TD Lee Fellow and associate professor at the TD Lee Institute and the Department of Astronomy at Shanghai Jiao Tong University. His main focus is to understand the atmospheric dynamics and climate of exoplanets and brown dwarfs using theories and numerical simulations. He obtained his B.S. at the University of Science and Technology of China, his Master's at the University of Hong Kong, and his Ph.D. at the University of Arizona. Before joining SJTU, he was a postdoctoral researcher at the Department of Physics, University of Oxford.
