Theory of spots on chemically peculiar stars
EAS Publications Series, 2014Surface inhomogeneities are found in many stars. In active sun-like stars and cool giants temperature spots similar to that found in the Sun are recovered from the inversion of spectroscopic data. M-dwarfs also show highly inhomogeneous surface structures in polarized light and photometric variability that are believed to be connected with cool regions

Atmospheric Variations in Chemically Peculiar Stars
1989The 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.

Magnetic field structures in chemically peculiar stars
Astrophysical Bulletin, 2011We report the results of magnetic field modelling of around 50 CP stars, performed using the “magnetic charges” technique. The modelling shows that the sample reveals four main types of magnetic configurations: 1) a central dipole, 2) a dipole, shifted along the axis, 3) a dipole, shifted across the axis, and 4) complex structures. The vast majority of
