Notes. Explanation of the columns: planet’s radius (1), mass (2), zero-albedo equilibrium temperature (3), average orbital distance(1) (4), ATES (in bold) vs. TCPI (in brackets) mass outflow rate (5), host star mass (6), X-ray (7), and EUV luminosity (8).
References. The planets considered in this work, along with their parameters, are drawn from S16, and references therein. Starting from a list of 21 targets (see Table 1 in S16), we limit our list to those which are estimated to have out-flowing (rather than stable) atmospheres, i.e. targets 1–14 in Table 3 of S16. The mass outflow rates obtained by ATES are shown in boldface, next to the TPCI values by S16, in brackets (see Fig. 10 for a visual comparison). ( * )Refers to the volumetric mean radius RJ = 6.99 × 109 cm.
