Astrophysics Aims and scope

Abstract

A short review on diffusion processes in atmospheres of stars is given. The diffusion model and its application for interpretation of spectral features of Am and Ap stars are described schematically. The building of abundance stratification and the case of calcium in Am stars are described briefly.
