Caroline Piaulet is in the third year of a Physics Bachelor Degree program at Université de Montréal. Recipient of one of the 2018 Trottier Excellence grants, she is doing a summer internship in the iREx research group, under the supervision of Björn Benneke.
During the summer, she will carry out a project related to the study of exoplanet atmospheres. She will first apply a retrieval framework, designed to determine the atmosphere composition and cloud properties of exoplanets, on simulated JWST (James Webb Space Telescope) data, in order to evaluate the quality of the information that can be expected to be retrieved in the future based on these higher-quality spectra. In particular, she will investigate how retrieval results can be affected by the assumption of a non-uniform atmosphere. Then, she is going to apply the atmosphere retrieval method on spectra obtained with the NIRSPEC (Near Infra-Red SPECtrograph) instrument of the Keck II 10m telescope, which are direct observations of planetary-mass companions, in order to study their atmospheres in greater detail.
