Radiative accelerations (in cm s^-2) of Sc for a solar abundance vs. the depth (temperature T is in K). The solid line corresponds to the radiative acceleration calculated in this work when using the SVP method, the long-dashed line to the aceleration obtained with the GLAM method, the short-dashed line to the calculation of LeBlanc & Alecian (2008). Also shown are the approximate locations of the bottom of the convection zones of Scenarios A and B. The dotted line represents the local gravity, the dash-dot line the effective gravity g_GT as defined by Eq. (8) of Michaud et al. (1976), and the dash-dot-dot line the effective gravity g_GT with the (R/r)² factor and the electronic pressure of our model (see footnote [4]).
