Complementarity between JWST and High Resolution Spectroscopy for characterization of Hot Jupiter Atmosphere

Hot Jupiters are giant gaseous planets, which orbit their host stars in a few days to hours. Due to these tight orbits, they are expected to rotate synchronously, ie always present the same face to their star. As a consequence, models predict these worlds to present strong westward winds, redistributing the heat from their permanent daysides to their cold nightsides. While indirect
jmethods have been used to corroborate these predictions, direct measurements of rotation/wind speeds on these objects remain
!elusive. ln this project, we aim to develop a novel method combining existing space and ground based approaches, which should
[allow for the first direct and constraining measurements of rotation and wind speeds in a Hot Jupiter atmosphere.
