IAA-CSIC offers a postdoc contract in the framework of the Project “Severo Ochoa”. Candidates are expected to carry out their activity in the field of characterization of the atmospheres of exoplanets by using high resolution spectroscopy, e.g. with data from instruments such as CARMENES, CRIRES+ or EXPRESSO. Work is expected to be focussed on detection of atoms and molecules, characterize the thermal structure and the upper atmospheres of planets undergoing hydrodynamic scape. Tasks: - Analysis of high-resolution observations of transiting planets in the visible and near infrared.
