Absolute Dimensions and Apsidal Motion of the Eccentric Binary V731 Cephei
V. Bakis, M. Zejda, I. Bulut +7
A detailed analysis of new and existing photometric, spectroscopic and spatial distribution data of the eccentric binary V731 Cep was performed. Spectroscopic orbital elements of t…
The record-breaking rotational braking of the He strong CP star HD 37776
Z. Mikulasek, J. Krticka, J. Zverko +8
We study the long-term light and spectral variations in the He-strong magnetic chemically peculiar star HD 37776 (V901 Ori) to search for changes of its 1.5387 d period in 1976-200…
Eclipsing Binaries with Possible Light-Time Effect
Zasche Petr, Zejda Miloslav, Brat Lubos
The period changes of six eclipsing binaries have been studied with focus on the light-time effect. With the least squares method we also calculated parameters of such an effect an…
The ZOO of uvby and Hp light curves of magnetic chemically peculiar stars
Z. Mikulasek, J. Zverko, J. Krticka +3
We present preliminary results of the generalized Principal Component Analysis (PCA) of light curves of 82 magnetic chemically peculiar (further mCP) stars applied to 54 thousand i…
Preliminary analysis of photometric variations of central star of planetary nebula Sh 2-71
Zdenek Mikulasek, Lubos Kohoutek, Miloslav Zejda +1
We confirmed the presence of regular UBVRIc light variations of the object in the centre of planetary nebula Sh 2-71, the improved period of them being P =(68.132+/-0.005) days. Th…
