[PEM11-01] Toward linking exoplanetary atmospheres to planet formation in the era of JWST
★Invited Papers
キーワード:系外惑星、大気、JWST、惑星形成
One of the main motivations of observing exoplanets is to understand planet formation and evolution process. In particular, the chemical compositions of exoplanetary atmospheres provide valuable clues to where and how the planet was formed. The James Webb Space Telescope (JWST) is revolutionizing our understanding on exoplanetary atmospheres thanks to its unprecedented precision and wavelength coverage. In this talk, I will first introduce several results of recent observations of JWST for hot Jupiter WASP-39 b and warm Jupiter WASP-80 b and its implications on the chemical inventory of their atmospheres.
While the observational data quality is going to grow rapidly in the coming decade, it is not straightforward to infer the planet formation process from atmospheric observations. In the rest of my talk, I will introduce several outstanding caveats regarding the way to infer the past formation process from exoplanetary atmospheres, such as the thermal structure of protoplanetary disks and disequilibrium chemistry in exoplanetary atmospheres.
