Left: Hertzsprung–Russell diagram showing the MESA single-star evolutionary track of TOI-5882 colored by age (color bar in Gyr), starting from the zero-age main sequence and evolving to the tip of the red-giant branch. The present-day position of TOI-5882 is marked with a red star. Diagonal dotted lines of constant radii indicate the present-day orbital separation of TOI-5882b (gray) alongside the stellar radii at the onset of Roche-lobe overflow (RLOF) as predicted by the differing tidal prescriptions. Right: orbital period decay as a function of time from the present day for the four different tidal prescriptions.
