The field of exoplanet science has long since shifted its focus from just detection onto characterisation, although characterisation remains extremely challenging. Thus far, the majority of research into characterisation has been directed towards modelling, or studies focusing on one or a few exoplanets. This new work, led by researchers based at University College London (UCL), used the largest amount of archival data ever examined in a single exoplanet atmosphere survey to analyse the atmospheres of 25 exoplanets. ...
The science team sought to find answers to five open questions about exoplanet atmospheres — an ambitious goal that they succeeded in reaching. Their questions probed what H– and certain metals can tell us about the chemistry and circulation of exoplanet atmospheres, and about planet formation. They chose to investigate a wide range of hot Jupiters, with the intention of identifying trends within their sample population that might provide insight into exoplanet atmospheres more generally. ...
