Revisiting BV & BW Draconis: Detailed Study of Intriguing Multiple System
J. J. Tokarek, W. Dimitrov, M. Polińska +6
The BV & BW Draconis system is a unique coplanar system of two eclipsing contact binaries. The main objective of this study is to develop a model based on new observations. The onl…
Recent humps and superhumps observations and an estimation of outburst parameters of the AM CVn star CR Boo
Daniela Boneva, Radoslav Zamanov, Svetlana Boeva +4
We present our observational results of AM CVn star CR Boo in the UBVR bands. Our observational campaign includes data obtained over 5 nights with the National Astronomical Observa…
Ori and Lib: Two new massive heartbeat binaries
Andrzej Pigulski, Monika K. Kaminska, Krzysztof Kaminski +28
We report the discovery of two massive eccentric systems with BRITE data, Ori and Lib, showing heartbeat effects close to the periastron passage. Lib exhibits shallow e…
Interplay between pulsations and mass loss in the blue supergiant 55 Cygnus = HD 198478
M. Kraus, M. Haucke, L. S. Cidale +14
Blue supergiant stars are known to display photometric and spectroscopic variability that is suggested to be linked to stellar pulsations. Pulsational activity in massive stars str…
A search for pulsations in the HgMn star HD 45975 with CoRoT photometry and ground-based spectroscopy
T. Morel, M. Briquet, M. Auvergne +28
The existence of pulsations in HgMn stars is still being debated. To provide the first unambiguous observational detection of pulsations in this class of chemically peculiar object…
Absolute properties of the main-sequence eclipsing binary FM Leo
M. Ratajczak, T. Kwiatkowski, A. Schwarzenberg-Czerny +9
First spectroscopic and new photometric observations of the eclipsing binary FM Leo are presented. The main aims were to determine orbital and stellar parameters of two components…
