Abstract: TESS has discovered a large number of close-in giant planets in the last five years. I will discuss how these discoveries renovate our understanding of hot and warm Jupiter's origins. The orbital eccentricity, stellar obliquity, multiplicity, and atmospheric composition of these close-in giant planet systems lead us to a comprehensive view of their origin channels. I will discuss population-level statistics and individual system discoveries that help build the complete picture.

Bio: Jiayin Dong （董佳音）is a postdoctoral fellow at the Center for Computational Astrophysics (CCA) at Flatiron Institute. Before this, she obtained her Ph.D. degree in Astronomy & Astrophysics from Penn State and her undergraduate degrees in Engineering Physics and Astronomy from the University of Illinois at Urbana-Champaign. Jiayin's research interests lie in exoplanets and planet formation, with a particular focus on the study of hot and warm Jupiters.
