O článku:
The atmospheric structure of chemically peculiar stars deviates from that of normal
stars with similar fundamental parameters due to unusual chemistry, abundance
inhomogeneities and the presence of strong magnetic field. These effects are not considered
in the standard model atmospheres, possibly leading to large errors in
stellar parameter determination and abundance analysis. To resolve this problem
we used the state-of-the-art opacity sampling model atmosphere code
LLmodels to calculate a comprehensive grid of new generation model
atmospheres for magnetic CP
stars. This grid
covers the whole parameter space occupied by SrCrEu and Si-peculiar stars, taking
into account the characteristic temperature dependence of the chemical abundances.
Here we present the first results of our model atmosphere calculations.
