Abstract:We present the photometric and spectroscopic analysis of four W UMa binaries J015829.5+260333 (hereinafter as J0158), J030505.1+293443 (hereinafter as J0305), J102211.7+310022 (hereinafter as J1022) and KW Psc. The V R c I c band photometric observations are carried out with the 1.3-m Devasthal Fast Optical Telescope (DFOT). For low resolution spectroscopy, we used 2-m Himalayan Chandra Telescope (HCT) as well as the archival data from 4-m LAMOST survey. The systems J0158 and J0305 show a period increase rate … Show more
