First apsidal motion and light curve analysis of 162 eccentric eclipsing binaries from LMC
P. Zasche, M. Wolf, H. Kučáková +6
We present an extensive study of 162 early-type binary systems located in the LMC galaxy that show apsidal motion and have never been studied before. For the ample systems, we perf…
Towards comprehension of the variability of the magnetic chemically peculiar star CU Virginis (HD 124224)
Zdeněk Mikulášek, Jiří Krtička, Andrzej Pigulski +2
The upper main sequence stars CU Virginis is the most enigmatic object among magnetic chemically peculiar (mCP) stars. It is an unusually fast rotator showing strictly periodic lig…
What is New with Landstreet Star HD 37776 (V901 Ori)?
Zdeněk Mikulášek, Jiří Krtička, Matthew E. Shultz +6
HD\,37776 (V901\,Ori, B2\,Vp), also known as Landstreet's Star, is possibly the most remarkable magnetic chemically peculiar (mCP) star known. Zeeman Doppler Imaging revealed this…
Hot subdwarf wind models with accurate abundances I. Hydrogen dominated stars HD 49798 and BD+182647
J. Krticka, J. Janik, I. Krtickova +5
Hot subdwarfs are helium burning objects in late stages of their evolution. These stars can develop winds driven by light absorption in the lines of heavier elements. The wind stre…
An overview of the properties of a sample of newly-identified magnetic chemically peculiar stars in the Kepler field
Zdeněk Mikulášek, Ernst Paunzen, Stefan Hümmerich +4
We present a comprehensive overview of the properties of a sample of 41 magnetic chemically peculiar stars that have been recently identified in the Kepler field by our team (Hümme…
Search for stellar spots in field blue horizontal-branch stars
E. Paunzen, K. Bernhard, S. Huemmerich +3
Blue horizontal-branch stars are Population II objects which are burning helium in their core and possess a hydrogen-burning shell and radiative envelope. Because of their low rota…
The Kepler view of magnetic chemically peculiar stars
Stefan Hümmerich, Zdenek Mikulášek, Ernst Paunzen +6
Magnetic chemically peculiar (mCP) stars exhibit complex atmospheres that allow the investigation of such diverse phenomena as atomic diffusion, magnetic fields, and stellar rotati…
CzeV - The Czech Variable Star Catalogue
Marek Skarka, Martin Mašek, Luboš Brát +62
We present the first release of the Czech Variable star catalogue that currently contains 1228 stars whose variability was discovered by 60 Czech observers. The catalogue contains…
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…
