Description
Low-mass exoplanets are showing a diversity in their densities and irradiation conditions, ranging from highly irradiated planets to temperate worlds. To estimate their composition, we have developed an interior structure model that includes self-consistently an atmosphere in radiative-convective equilibrium for water and CO$_{2}$ envelopes. We use the model within a Bayesian adaptive Markov Chain Monte Carlo (MCMC) to estimate the uncertainties of the core and water mass fraction for a sample of multiplanetary systems, which gives us clues about their possible formation site in the protoplanetary disk and their formation mechanisms, as well as assess their observability with JWST.
