New absolute magnitude calibrations for W Ursa Majoris type binaries
Z. Eker, S. Bilir, E. Yaz +2
Parallaxes of W UMa stars in the Hipparcos catalogue have been analyzed. 31 W UMa stars, which have the most accurate parallaxes () which are neither associated with a…
New absolute magnitude calibrations for detached binaries
S. Bilir, T. Ak, E. Soydugan +6
Lutz-Kelker bias corrected absolute magnitude calibrations for the detached binary systems with main-sequence components are presented. The absolute magnitudes of the calibrator st…

Chromospherically Active Binaries (CAB) catalogue have been revised and updated. With 203 new identifications, the number of CAB stars is increased to 409. Catalogue is available i…
Formation and Evolution of W UMa Stars: Fallacies and Corrections
Z. Eker, O. Demircan, S. Bilir
The period histograms of eclipsing binaries generated with ASAS data cannot only be interpreted by orbital evolution. The eclipse probabilities, selection effects and space distrib…
