Table 1: Observational parameters for T Tauri stars (from Bouvier 1990; Hartmann et al. 1998) and for FU Ori stars (from Popham et al. 1996) considered in this study ( left) and disk physical parameters ( right). The computation of the corotation radius requires the knowledge of the stellar rotation velocity. In case this last quantity is not available, the corotation radius has been set to $10.05~ R_\odot$ , the solar value. Lower and upper bound on $\dot M_0$ and Re have been computed using either the star radius or the corotation radius for $r_{\rm i}$ . Accretion rates are in $M_\odot$ yr^-1.
