Candidates for RR~Lyrae in binary systems from the OGLE Galactic bulge survey
Z. Prudil, M. Skarka, J. Liška +2
We present 20 newly discovered candidates for binary systems with an RR~Lyrae companion. Using the photometric data from the Optical Gravitational Lensing Experiment (OGLE) and Kor…
A cautionary tale of interpreting O-C diagrams: period instability in a classical RR Lyr Star Z CVn mimicking as a distant companion
M. Skarka, J. Liška, R. Dřevěný +4
We present a comprehensive study of Z CVn, an RR Lyrae star that shows long-term cyclic variations of its pulsation period. A possible explanation suggested from the shape of the O…
New inclination changing eclipsing binaries in the Magellanic Clouds
J. Juryšek, P. Zasche, M. Wolf +8
Context: Multiple stellar systems are unique laboratories for astrophysics. Analysis of their orbital dynamics may reveal invaluable information about the physical properties of th…
Possible candidates for multiple occurrence of variable stars in the VSX catalogue
Jiri Liska, Marek Skarka, Reinhold Friedrich Auer +2
A paper about variable stars with possible multiple occurrence in the VSX catalogue is presented. Our main criteria for identification of such duplicities were the angular distance…
