Context. Magnetic chemically peculiar (mCP) stars exhibit complex atmospheres that allow
the investigation of such diverse phenomena as atomic diffusion, magnetic fields, and stellar …

We present results of an abundance and stratification analysis of the weakly magnetic
chemically peculiar star HD 204411 based on the echelle spectrum obtained with the high …

Context. Although photometric variations of chemically peculiar (CP) stars are frequently
used to determine their rotational periods, the detailed mechanism of their light variability …

To enlarge our data base of chemically peculiar stars, we compiled published data
concerning the He-weak and He-rich stars observed by high-resolution spectroscopy …

Context. Historically, stellar model atmospheres with scaled solar abundances (for all
elements heavier then helium) have been widely used for analysis of the atmospheres of …

Context. The presence of heavier chemical elements in stellar atmospheres influences the
spectral energy distribution of stars. An uneven surface distribution of these elements …

Context. Magnetic chemically peculiar (mCP) stars exhibit complex atmospheres that allow
the investigation of the interplay of atomic diffusion, magnetic fields, and stellar rotation. A …

Context. The magnetic chemically peculiar (mCP) stars of the upper main sequence are
perfectly suited to studying the effects of rotation, diffusion, mass-loss, accretion, and …

In this paper, we present new specific stellar models for the Large Magellanic Cloud. In
order to take the observational uncertainties in the chemical composition into account, we …

Model atmospheres of A and B stars are computed taking into account magnetic line
blanketing. These calculations are based on the new stellar model atmosphere code …
