- Abstract
The atmospheres of magnetic Ap stars (chemically peculiar stars) are supposed to be inhomogeneous in chemical abundances. This prediction of the atomic diffusion hypothesis is confirmed by recent observations. However, numerical modelling of these stratifications is very difficult, especially for atmospheres with strong magnetic fields. We present here preliminary results of abundance stratifications (equilibrium solutions) obtained for the first time by detailed calculations including magnetic fields.
