This is the first paper of the series dedicated to the analysis of the magnetism of chemically peculiar (CP) stars of the upper Main Sequence. We use our own measurements and …
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 …
II Romanyuk - Astrophysical Bulletin, 2007 - Springer
This paper continues a series of reviews dedicated to magnetic CP stars. The occurrence frequency of CP stars among B5–F0-type main-sequence stars is shown to be equal to …
The dependence of the degree of anomaly of parameter Z of Geneva photometry (Z 0= Z CP ℒ Z norm.) on the average surface magnetic field Bs is analyzed. The Z 0 value is …
Surface helium and silicon distribution of a He-weak CP star HD21699 was examined using the spectra obtained at different phases of the star's rotational period. The abundance of …
Our spectrophotometric analysis of the atmospheres of HD 37058, HD 212454, and HD 224926 shows these objects to be typical He-w stars with close-to-zero microturbulence …

Our observations with the 6-m telescope revealed six new magnetic chemically peculiar (CP) stars among objects with large depressions in the continuum: HDE 293764, BD+ 17° …
YV Glagolevskii, TA Ryabchikov, GA Chountonov - Astronomy Letters, 2005 - Springer
We analyzed the chemical composition of the chemically peculiar (CP) star HD 0221= 43 Cas using spectra taken with the NES spectrograph of the 6-m telescope with a spectral …
