XUV irradiation of TRAPPIST-1 planets.
|(5−100 Å)||(100−912 Å)|
Notes. Fluxes in erg s-1 cm-2, hydrogen photoionization rate Γion in ×10-6 s-1, mass loss rate Ṁtot in 106 g s-1. X-ray flux is derived from Wheatley et al. (2017). The mass of TRAPPIST-1 h is unconstrained, and we did not estimate its mass-loss rate. Uncertainties on the EUV flux were estimated by accounting for both the uncertainty on the Ly-α flux and the Linsky et al. (2014) relation.
