Surface structure of the CoRoT CP2 target star HD 50773
T. Lüftinger, H. -E. Fröhlich, W. Weiss +15
We compare surface maps of the chemically peculiar star HD 50773 produced with a Bayesian technique and based on high quality CoRoT photometry with those derived from rotation phas…
The Lorentz force in atmospheres of CP stars: 56 Arietis
D. Shulyak, O. Kochukhov, G. Valyavin +5
The presence of electric currents in the atmospheres of magnetic chemically peculiar (mCP) stars could bring important theoretical constrains about the nature and evolution of magn…
Improved fundamental parameters and LTE abundances of the CoRoT solar-type pulsator HD49933
T. Ryabchikova, L. Fossati, D. Shulyak
The knowledge of accurate stellar parameters is a key stone in several fields of stellar astrophysics, such as asteroseismology and stellar evolution. Although the parameters can b…
A self-consistent empirical model atmosphere, abundance and stratification analysis of the benchmark roAp star alpha Circini
O. Kochukhov, D. Shulyak, T. Ryabchikova
Chemically peculiar (CP) stars are unique natural laboratories for investigation of the microscopic diffusion processes of chemical elements. The element segregation under the infl…
Model atmospheres of chemically peculiar stars: Self-consistent empirical stratified model of HD24712
D. Shulyak, T. Ryabchikova, L. Mashonkina +1
High-resolution spectra of some chemically peculiar stars clearly demonstrate the presence of strong abundance gradients in their atmospheres. However, these inhomogeneities are us…
