Notes. The value S∕S⊙
is the ratio of the total stellar irradiance to the TSI to reach a surface temperature of 288.15 K. The transit duration was calculated via Eq. (7). We assume circular orbits for all planets. The transit depth,
, is calculated using the stellar radii from Table 1 and the radius of the Earth. The equilibrium temperature (Teq) was calculated using the corresponding planetary albedo (αp).
