报告摘要：Giant planets like hot Jupiters are the easiest planets to find, which is why the first discovered extrasolar planets are all giants. Three decades later, we now know over a thousand giant planets. However, there are still numerous mysteries around their formation, evolution, and their impact on their natal planetary systems. In this talk, I will introduce my group’s recent research on how special samples of giants would shed light on some of the clues in their formation and evolutionary processes, focusing on unique opportunities enabled by the TESS survey and ground-based radial velocity observations.

主讲人简介：Xuesong (Sharon) Wang is an Associate Professor in the Department of Astronomy at Tsinghua University. She joined the department in 2020 and was previously a Carnegie Fellow at Carnegie DTM (now EPL) and the Observatories. She received her Ph.D. from the Pennsylvania State University and a B.S. in Physics from Tsinghua. Her group at Tsinghua, the ExoLab, focuses on observational studies of exoplanets, primarily using the transit and radial velocity (RV) methods. She is the Project Scientist for the next-generation precise RV spectrograph, CHORUS, that China is currently building for the 10.4-meter GTC, as well as a science team member for multiple RV programs such as Magellan/PFS, Keck/KPF and WIYN/NEID.
