Özet

The early-type contact binary DU Boo exhibits consistent O’Connell effect for many years. Studies in the literature of the system are insufficient to explain this consistency in the observed O’Connell effect. Based on this gap in the literature, the aim of this study is to investigate the surface brightness distribution of the system using the Doppler imaging technique as well as the mid-resolution time series spectra.
