Magnetic field structures in chemically peculiar stars

Astrophysical Bulletin, 2011
We 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

Theory of spots on chemically peculiar stars

EAS Publications Series, 2014
Surface 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

The chemically peculiar stars of the upper main sequence

Nuclear Instruments and Methods, 1973
Abstract Abundance anomalies of two classes of peculiar main sequence stars are reviewed. The anomalies include gross overabundances of some elements and deficiencies of others. Isotopic abundances of three elements appear to be abnormal.

Chemically peculiar stars investigated by the BRITE mission

Since the discovery of the spectral peculiarities of their prototype alpha 2 Canum Venaticorum in 1897, the so-called ACV variables, which are comprised of several groups of chemically peculiar (CP) stars of the upper main sequence, have been the target of numerous photometric and spectroscopic studies.
