Notes. Temperatures refer to the model stars described in Sect. 4.2, based on the pre-main sequence tracks of Tognelli et al. (2011). The excess UV for the 4000 and 6000 K stars is for an accretion rate Ṁ= 10-8M⊙ yr-1; the energy is released on the stellar surface at 10 000 K effective temperature. The Lymanα luminosity of TW Hya, integrated from 121 to 122 nm, is 5.1 × 10-3L⊙.
