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…
Spectroscopic survey of Kepler stars. I. HERMES/Mercator observations of A- and F-type stars
E. Niemczura, S. J. Murphy, B. Smalley +21
The Kepler space mission provided near-continuous and high-precision photometry of about 207,000 stars, which can be used for asteroseismology. However, for successful seismic mode…
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…
mu Eridani from MOST and from the ground: an orbit, the SPB component's fundamental parameters, and the SPB frequencies
M. Jerzykiewicz, H. Lehmann, E. Niemczura +15
MOST time-series photometry of mu Eri, an SB1 eclipsing binary with a rapidly-rotating SPB primary, is reported and analyzed. The analysis yields a number of sinusoidal terms, main…
Four unusual novae observed in Torun: V2362 Cyg, V2467 Cyg, V458 Vul, V2491 Cyg
E. Ragan, M. Mikolajewski, T. Tomov +21
We present photometric and spectral observation for four novae: V2362 Cyg, V2467 Cyg, V458 Vul, V2491 Cyg. All objects belongs to the "fast novae" class. For these stars we observe…
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…
V440 Per: the longest period overtone Cepheid
R. Baranowski, R. Smolec, W. Dimitrov +9
V440 Per is a Population I Cepheid with the period of 7.57 day and low amplitude, almost sinusoidal light and radial velocity curves. With no reliable data on the 1st harmonic, its…
