Fig. B.1

Study of the stellar properties of RY Tau. Top panels: the optical EXPORT spectrum (black) compared to a synthetic model (red) with Teff = 5750 K, log (g) = 3.58, and v ×sin (i) = 52 km s−1. Third panel: the different values of optical extinctions AV and stellar luminosities obtained by adopting different brightnesses in the V band as a photospheric level. Fourth panel: the de-reddened SED of the source with different values of V mag, and thus AV. A reasonable fit to the optical photometry and agreement with the NIR photometry is obtained only with V = 10.0 and V = 10.4. The stellar model is obtained for V = 10.0 and AV = 1.5 and corresponds to a stellar luminosity L* = 6.3 L⊙.
