Featureless transmission spectra of 12 giant exoplanets observed by GTC/OSIRIS [PDF]

open access: yesA&A 675, A62 (2023), 2023
Exoplanet atmospheres are the key to understanding the nature of exoplanets. To this end, transit spectrophotometry provides us opportunities to investigate the physical properties and chemical compositions of exoplanet atmospheres. We aim to detect potential atmospheric signatures in 12 gaseous giant exoplanets using transit spectrophotometry and we ...
