Notes. The table shows spectral type, distance d, interstellar extinction AV, effective temperature Teff, stellar luminosity L, stellar mass M, age, and UV and X-ray luminosities without extinction, i.e. as seen by the disk. Numbers written A(−B) mean A × 10B. The UV and X-ray luminosities are listed in units of (L). (1)Spectral types, ages and stellar masses are consistent with evolutionary tracks for solar-metallicity premain sequence stars by Siess et al. (2000), using Teff & L as input, (2)FUV luminosity from 91.2 to 205 nm, as seen by the disk, (3)hard FUV luminosity from 91.2 to 111 nm, as seen by the disk, (4)X-ray luminosity for photon energies > 0.1 keV, as seen by the disk, (5)hard X-ray luminosity from 1 keV to 10 keV, as seen by the disk, (6)no matching track, values from closest point at Teff = 9650 K and L = 42 L, (7)no matching track, values from closest point at Teff = 10 000 K and L = 42 L, (8)no UV data, model uses an UV-powerlaw with fUV = 0.025 and pUV = 0.2 (see Woitke et al. 2016) (9)no detailed X-ray data available, model uses a bremsstrahlungs-spectrum with LX = 8.8 × 1028 erg s−1 and TX = 20 MK, based on archival XMM survey data (M. Güdel, priv. comm.), (10)“low-UV state” model, where a purely photospheric spectrum is assumed, (11)no X-ray data available, X-ray data taken from HD 97048, (12)no matching track, values from closest point at Teff = 7050 K and L = 7 L, (13)no X-ray data available, (14)resolved binary, 2× spectral type M1, luminosities 0.69 L and 0.56 L, separation 0.094″ ≈ 13 AU (Hillenbrand & White 2004), (15)derived from fitting our UV, photometric optical and X-ray data (16)no matching track, values taken from (Drabek-Maunder et al. 2016; Kraus et al. 2012), (17)no UV data, model uses fUV = 0.01 and pUV = 2 (see Woitke et al. 2016, Appendix A for explanations), (18)no X-ray data, model uses LX = 1030 erg s−1 and TX = 20 MK (see Woitke et al. 2016, Appendix A for explanations).
