Modelling of the ultraviolet and visual SED variability in the hot magnetic Ap star CU Vir
J. Krticka, Z. Mikulasek, T. Luftinger +4
The spectral energy distribution (SED) in chemically peculiar stars may be significantly affected by their abundance anomalies. The observed SED variations are usually assumed to b…
Surprising variations in the rotation of the chemically peculiar stars CU Virginis and V901 Orionis
Zdenek Mikulasek, Jiri Krticka, Gregory W. Henry +13
CU Vir and V901 Ori belong among these few magnetic chemically peculiar stars whose rotation periods vary on timescales of decades. We aim to study the stability of the periods in…
Magnetic Chemically Peculiar Stars with Unsteady Periods
Zdenek Mikulasek, Jiri Krticka, Jan Janik +4
Photometrically and spectroscopically variable chemically peculiar (CP) stars are the optimum laboratories for testing the rotational evolution of main sequence stars. A vast major…
Rotational periods of magnetic chemically peculiar stars
Zdenek Mikulasek, Gabriel Szasz, Jiri Krticka +4
Magnetic chemically peculiar (mCP) stars of the upper part of the main sequence usually exhibit strictly periodic variations of their light, spectrum and magnetic field. These chan…
The nature of the light variability of the silicon star HR 7224
J. Krticka, Z. Mikulasek, G. W. Henry +4
Although photometric variations of chemically peculiar (CP) stars are frequently used to determine their rotational periods, the detailed mechanism of their light variability remai…
Photometrically simply behaving mCP stars
Z. Mikulasek, T. Graf, J. Krticka +2
We analyzed uvby and Hp light curves of 19 well observed magnetic CP stars selected from the "On-line database of photometric observations of mCP stars" of which light curves in al…
