Chemical abundances of Cephei stars from low- and high-resolution UV spectra
Jadwiga Daszy{ń}ska-Daszkiewicz, Ewa Niemczura
In early type stars the ultraviolet spectral region is important for several reasons. Firstly, since the majority of the total flux is emitted here, it provides a rather sensitive…

On application of multi-colour photometry of Scuti stars
J. Daszy{ń}ska-Daszkiewicz, W. A. Dziembowski, A. A. Pamyatnykh
In Scuti star models, the photometric amplitudes and phases exhibit a strong dependence on convection, which enters through the complex parameter, , which describes the bolo…

Searching for Line Profile Variability in HgMn Stars
S. Turcotte, C. Aerts, P. Knoglinger
Spectra of four non-magnetic chemically peculiar late B type stars (HgMn) stars are analysed to detect periodic spectral line variations (LPVs). A procedure developed to study LPVs…
