Abstract

The expression ‘Chemically Peculiar Stars’ was established by Preston in 1974 to group together the various types of stars with abnormal chemical composition on the upper main sequence. In this volume Maitzen (1989) gives a compilation of the variety of photometric and spectroscopic properties of all subtypes of CP stars. This paper deals exclusively with the classical Ap stars, stars in the spectral range from F to B that show magnetic fields, the CP2 stars in Prestons notation. In these stars we have the possibility to study the interaction of a stellar photosphere with a strong, large scale magnetic field.
