Bu çalışmada, V765 Aur ve V638 Vir örten çift yıldız sistemlerinin ışık eğrisi çözümleri ilk defa sunulmuştur. Gözlemsel veri olarak Transiting Exoplanet Survey Satellite (TESS) uydu gözlemleri kullanılmıştır. Işık eğrisi çözümlerinden V765 Aur ve V638 Vir kaynaklarını oluşturan her iki bileşenin de kendi Roche loblarını doldurmadıkları görülmüştür. Çözüm parametreli kullanılarak ele alınan sistemlerin mutlak parametre değerleri tahmin edilmiştir. Buna göre, V765 Aur sistemini oluşturan birinci ve ikinci bileşenlerin kütle ve yarıçap değerleri, sırasıyla, M_1=1.58±0.16 M_⊙, R_1=1.47±0.12 R_⊙ ve M_2=0.46±0.10 M_⊙ , R_2=1.27±0.26 R_⊙ olarak hesaplanmıştır. V638 Vir sisteminin birinci ve ikinci bileşenlerinin kütle ve yarıçap değerleri ise M_1=1.23±0.12 M_⊙, R_1=1.63±0.11〖 R〗_⊙ ve M_2=0.16±0.06 M_⊙, R_2=1.40±0.23 R_⊙ değerlerinde elde edilmiştir.
