Description

GASTLI is a user-friendly Python package developed to support both observers and expert modelers in modeling of exoplanet interiors with volatile-rich envelopes. GASTLI generates mass-radius and thermal evolution curves (radius-age) as well as interior and atmosphere structure profiles. GASTLI’s key features include up-to-date equations of state, flexible mass, composition and irradiation inputs, a customisable atmospheric grid and the possibility to perform retrievals on mass, radius, age and atmospheric metallicity data.
