Abstract:

Our recent ground-based BVRI CCD observations of the eclipsing binary system EL Aqr provide the most accurate photometric light variation obtained so far for this system. In addition to the photometric observations, a revision of all existing spectroscopic data is carried out and a new mass ratio is derived. The combined photometric and spectroscopic data are analyzed using the Wilson- Devinney light curve synthesis code and new geometric and photometric elements are calculated. EL Aqr is found to be in contact configuration, showing partial eclipses, and one of the smallest mass ratios ever found on contact binaries.
