Ivan L. Andronov, Vitalii V. Breus, Stanislaw Zola
During processing the observations of the intermediate polar 1RXS J180340.0+401214, obtained 26.05.2012 at the 60-cm telescope of the Mt. Suhora observatory (Krakow, Poland), varia…
Period variations the intermediate polars EX Hya, FO Aqr and RXS J180340.0+401214
Vitalii V. Breus, Ivan L. Andronov, Tibor Hegedus +4
We present results of CCD photometric study of the intermediate polars FO Aqr, EX Hya and RXS J180340.0+401214 = USNO-A2.0 1275-09738647 and corresponding corrected ephemerids.
Spectroscopic and Photometric Study of the Contact Binary BO CVn
S. Zola, R. H. Nelson, V. Senavci +4
We present the results of the study of the contact binary system BO CVn. We have obtained physical parameters of the components based on combined analysis of new, multi-color light…
A photometric and spectroscopic study of WW And - an Algol-type, long period binary system with an accretion disc
Michal Siwak, Stanislaw Zola, Tomasz Szymanski +5
We have analyzed the available spectra of WW And and for the first time obtained a reasonably well defined radial velocity curve of the primary star. Combined with the available ra…
