Conference Object Citation - WoS: 3Citation - Scopus: 3Photometric Multi-Site Campaign on Massive B Stars in the Open Cluster Chi Persei (ngc 884)(IOP Publishing, 2008) Saesen, S.; Pigulski, A.; Carrier, F.; De Ridder, J.; Aerts, C.; Handler, G.; Drummond, R.; Kalomeni, BelindaIn 2005 a photometric observation campaign started on the open cluster chi Persei, involving 13 telescopes spread over the whole northern hemisphere. After two years we gathered almost 1200 hours of data. We present here preliminary results on the variability search, especially from the 60-cm telescope in Bialkow (Poland), which show seven confirmed beta Cephei stars, four candidate B-type pulsators and other interesting variable stars.Conference Object Citation - WoS: 1Long-Term Monitoring of Polars(Cambridge University Press, 2011) Kalomeni, BelindaWe present long-term observations of magnetic cataclysmic variables AM Her, AN UMa, AR UMa, DP Leo, and V1309 Ori obtained with the ROTSEIIId telescope. All data have been analysed and preliminary results indicate periods of 170 days, 217 days, and 180 days for AM Her, AN UMa, and AR UMa, respectively. © International Astronomical Union 2012.Conference Object Evolution of Binaries Towards Hmxbs and Lmxbs(American Institute of Physics, 2011) Kalomeni, BelindaIn this study we investigate the evolution of binary systems towards low mass x-ray binaries and high mass x-ray binaries using Eggleton's binary star evolution code. © 2011 American Institute of Physics.Conference Object Magnetic Cataclysmic Variables(American Institute of Physics, 2010) Kalomeni, BelindaWe present a study on magnetic cataclysmic variables (polars) using the collected data from the literature. These parameters (mass, radius, magnetic field intensity, mass transfer rate, etc.) and the relations between them are important to understand their nature, to explain the observed properties of them and to test the current evolutionary models. © 2010 American Institute of Physics.Conference Object Citation - WoS: 2Citation - Scopus: 1Angular Momentum Loss in Polars(Cambridge University Press, 2009) Kalomeni, BelindaWe discuss the possible angular momentum loss mechanisms in AM Her type cataclysmic variables and their corresponding mass loss rates using the observed physical parameters of them.Conference Object Angular Momentum Loss by Magnetic Braking and Gravitational Radiation in Relativistic Binary Stars(Proceedings of Science (PoS), 2008) Yakut, Kadri; Kalomeni, Belinda; Tout, C. A.Angular momentum loss (AML) mechanisms and dynamical evolution owing to magnetic braking and gravitational radiation in relativistic binary stars (RBS) are studied with use of physical parameters collected from the literature. We have calculated and compared AML time scales for the RBS with non-degenerate components and double degenerate (DD) systems.
