Seminar by Jiayin Dong, CCA

Ever since the first discovery of a hot Jupiter, 51 Pegasi b, in 1995, the origin of close-orbiting giant planets has been a compelling topic of research. In this presentation, I will discuss recent advances in understanding their origins through the analysis of stellar obliquities, which is the angle between a planet’s orbital axis and its host star’s spin axis. I will share several recent exciting measurements and present their population-level stellar obliquity distribution. Our findings highlight planet-planet interactions as a significant mechanism in the formation of close-orbiting giant planets.
