Apsidal motion and TESS light curves of three southern close eccentric eclipsing binaries: GM Nor, V397 Pup, and PT Vel
M. Wolf, P. Zasche, J. Kára +10
New ground-based and space-based photometric data have been obtained and archival spectroscopic measurements were used in this study of three detached early-type and southern-hemis…
Kwee-van Woerden method: To use or not to use?
Zdeněk Mikulášek, Marek Chrastina, Miloslav Zejda +3
The trustworthiness of orbital period analyses of eclipsing binaries strictly depends on the correctness of the observed mid-eclipse time determination, as well the reliability of…
Ap stars with variable periods
Zdeněk Mikulášek, Jiří Krtička, Jan Janík +5
The majority of magnetic chemically peculiar (mCP) stars exhibit periodic light, magnetic, radio, and spectroscopic variations that can be adequately modelled as a rigidly-rotating…
Ultraviolet and visual flux and line variations of one of the least variable Bp stars HD 64740
J. Krticka, J. Janik, H. Markova +4
The light variability of hot magnetic chemically peculiar stars is typically caused by the flux redistribution in spots with peculiar abundance. This raises the question why some s…
Characterising the magnetic fields of the Herbig Ae/Be stars HD97048, HD150193, HD176386, and MWC480
S. Hubrig, M. Schoeller, I. Ilyin +6
Our knowledge of the presence and the role of magnetic fields in intermediate-mass pre-main-sequence stars remains very poor. We present the magnetic properties of four Herbig Ae/B…
Study of Eclipsing Binary and Multiple Systems in OB Associations: I. Ori OB1a - IM Mon
H. Bakis, V. Bakis, S. Bilir +5
All available photometric and spectroscopic observations were collected and used as the basis of a detailed analysis of the close binary IM Mon. The orbital period of the binary wa…
The X-ray emission from Z CMa during an FUor-like outburst and the detection of its X-ray jet
B. Stelzer, S. Hubrig, S. Orlando +3
Accretion shocks have been recognized as important X-ray emission mechanism for pre-main sequence stars. Yet the X-ray properties of FUor outbursts, events that are caused by viole…
