Table 3
Stellar parameters for HD 97658, GJ832, GJ1214 and the Sun.
| GJ1214 | GJ832 | SUN | HD 97658 | |
|---|---|---|---|---|
| Spectral type | M1.5V | M6V | G2V | K1V |
| M*, (Msun) | 0.15 | 0.45 | 1.00 | 0.77 |
| XUV flux at 1 AU [erg cm−2 s−1] | 0.12 | 1.07 | 4.40 | 11.47 |
| X-Ray flux (% XUV flux) | 9.4 | 15.8 | 12.9 | 2.8 |
| Rorbit (Rp) | 12 | 36 | 73 | 118 |
| M⋆/Mp | 239 | 717 | 1593 | 1227 |
| Ṁ with secondary ionisation [1011 g s−1] | 7.88 | 2.04 | 1.58 | 1.21 |
| M without secondary ionisation [1011 g s−1] | 16.6 | 3.95 | 2.78 | 2.08 |
| Mass-loss diminution | 52% | 48% | 43% | 41% |
Notes. Spectral type and M*, are taken from France et al. (2016). Mp and Rp refer to the M0.069 case. We also display the percentage of the XUV flux that goes into the X-ray flux (λ < 100 Å) and the 1D spherical mass-loss rates with and without the secondary ionisation by photoelectrons.
