Abstract

Monochromatic opacities from the OPAL database have been used to calculate radiative accelerations for the 21 included chemical species. The 104 frequencies used are sufficient to calculate the radiative accelerations of many elements for T [ 105 K, using frequency sampling. This temperature limit is higher for less abundant elements.
