**Radiative Accelerations in Stars **

This page is dedicated to userd ot a new method for fast and easy computations of radiative accelerations in stellar interiors. More detailed information about radiative accelerations in stars and this computation method is found here. The articles related to this method are the following:

The various parameters used in our approximate formulae have been calculated for the elements: C, N, O, Ne, Na, Mg, Al, Si, S, Ar, Ca and Fe in several stellar models (LeBlanc & Alecian 2004). The tables of these parameters are found here:

- T_eff = 8500 K, log g = 4.3 : svp_8500.dat
- T_eff = 10000 K, log g = 4.3 : svp_10000.dat
- T_eff = 12000 K, log g = 4.0 : svp_12000.dat

The various parameters for Sc found in a T_eff = 7610 K Am star (LeBlanc & Alecian 2008), along with the other elements considered in LeBlanc & Alecian (2004) are found here:

- T_eff = 7610 K, log g = 3.98 : svp_7610+Sc.dat

The values of the solar abundances used for these elements can be found here.
