R_p-P_orb diagram for exoplanets around cool stars (T_eff < 4000 K) taken from the NASA exoplanet archive. The solid and dashed lines represent respectively the Cloutier & Menou (2020) and Martinez et al. (2019) empirical radius valley (see text). The shaded region shows exoplanets that from their gas content could be able to test gas-depleted formation and thermally driven mass loss scenarios. TOI-1695 b is highlighted as a thick-lined black circle.
