Evolution of the MP, Menv, RP, and e of TOI-2257 b as a mini-Neptune. The initial 20,000 simulations were filtered out to identify cases whose final eccentricities and radii were within uncertainties, as seen in Table 2. This left 905 cases, but only ∼200 random cases are shown in the figure for clarity.
