First comprehensive study of W-type W UMa eclipsing binary V1036 Her

CCD photometry of the eclipsing binary system V1036 Her was performed using Johnson V filter in Dr. Mojtahedi Observatory University Birjand during July-August 2017 and July 2018. Moreover, spectroscopy carried out by TRES April A mass ratio 3.07(27)is obtained an initial effective temperature 5500 suggested. For first time, relative absolute parameters are determined analyzing light curve radial velocity data. The results indicate that is a W-subtype W UMa with degree overcontact 22%. analysis period change shows changes rate P˙=2.23(4)×10−7day/year. With assumption conservation, transfer from primary to secondary component m˙1=1.00(3)×10−7M⊙/year probable. Additionally, periodic behavior about 10 years observed O-C curve, which predicts possibility third body minimum 0.14(1)M⊙.
