A CCD Search for Variable Stars in the Open Cluster NGC 6611
G. Michalska, Z. Kołaczkowski, R. Leiton +4
We present the results of the variability survey in the young open cluster NGC 6611 based on observations obtained during 34 nights spanning one year. In total, we found 9…
BRITE observations of Centauri and Lupi, the first non-eclipsing members of the new class of nascent binaries
M. Jerzykiewicz, A. Pigulski, G. Michalska +8
Results of an analysis of the BRITE-Constellation and SMEI photometry and radial-velocity observations, archival and new, of two single-lined spectroscopic binary systems Centa…
Massive heartbeat stars from TESS. I. TESS sectors 1-16
Piotr Antoni Kołaczek-Szymański, Andrzej Pigulski, Gabriela Michalska +2
Heartbeat stars are eccentric binaries exhibiting characteristic shape of brightness changes during periastron passage caused by tidal distortion of the components. Variable tidal…
Ensemble asteroseismology of pulsating B-type stars in NGC 6910
D. Moździerski, A. Pigulski, Z. Kołaczkowski +24
Asteroseismology offers the possibility of probing stellar interiors and testing evolutionary and seismic models. Precise photometry and spectroscopy obtained during multi-site cam…
Variable Stars in Young Open Cluster NGC 2244
Gabriela Michalska
We present results of a UBVIc variability survey in the young open cluster NGC 2244. In total, we found 245 variable stars. Most of them, 211 stars, are variables with irregular va…
Variability survey in NGC 6910, the open cluster rich in Cephei-type stars
D. Moździerski, A. Pigulski, Z. Kołaczkowski +14
NGC 6910 is the northern hemisphere open cluster known to be rich in Cephei-type stars. Using four-season photometry obtained in Białków (Poland) and Xinglong (China) observato…
