چکیده انگلیسی


• The primary component is more massive and hotter than the secondary.
• The primary component showes a good fit with the M-R and M-L relations.
• There is an energy transfer from primary to secondary through the common convective envelope.

We present an orbital solution study for the newly discovered system 1SWASP J080150.03+471433.8 by means of new CCD observations in VRI bands. Our observations were carried out on 25 Feb. 2013 using the Kottamia optical telescope at NRIAG, Egypt. 12. New times of minima were estimated and the observed light curves were analysed using the Wilson–Devinney code. The accepted orbital solution reveals that the primary component of is more massive and hotter than the secondary one by about 30 K. The system is an over-contact one with fillout ratio ∼29% and is located at a distance of about 195 Pc. The evolutionary status of the system is investigated by means of stellar models and empirical data.
