•We present the analysis of spectroscopic and new photometric observations of GW Cnc.•The period changes in the Observed–Calculated (O–C) diagram were analyzed.•The orbital and physical parameters of the system were derived.•Our model describes GW Cnc as a W-type overcontact binary.
We present the results of our investigation on the geometrical and physical parameters of the W UMa type binary system GW Cnc. We analyzed the photometric data obtained in 2010 and 2011 at Ankara University Observatory (AUO) and the spectroscopic data obtained in 2010 at TUBITAK National Observatory (TUG) by using the Wilson–Devinney (2013 revision) code to obtain the absolute and geometrical parameters. We derived masses and radii of the eclipsing system to be M1=0.257M⊙,M2=0.971M⊙,R1=0.526R⊙ and R2=0.961R⊙ with an orbital inclination i(∘)=83.38±0.25i(∘)=83.38±0.25 and we determined the GW Cnc system to be a W-type W UMa over-contact binary with a mass ratio of q=3.773±0.007q=3.773±0.007.
