JADE exploration of TOI-672 b atmospheric evolution, assuming ages of 1, 5, and 10 Gyr (top, middle, and bottom rows, respectively). Left column : probability density function of the initial planet mass. The median is highlighted as an orange line, and the 1σ HDI interval is shown as dashed blue lines. Middle column : temporal evolution of the planet envelope mass in the best-fit simulation (orange curve) and a set of simulations from within the HDI interval (blue curves). The vertical black line with a grey shaded band marks the assumed age and uncertainties. Right column : same as the middle panel, but for the planet radius. The black point indicates the measured value.
