چکیده انگلیسی
We present the first photometric analysis for the newly discovered eclipsing binary systems of Algole-type GSC 2750-0054 and GSC 03208-02644. Our analysis was carried out by means of the most recent version of Wilson Devinney (WD) code, which applies the model atmosphere by (Kurucz, R., 1993. In: Milon, E. (Ed.), Light Curve Modeling of Eclipsing Binary Stars. Springer-Verlag, New York, p. 93) with a prescription in passband for the radiative treatment. The accepted light curve solutions reveal absolute physical parameters and the spectral classifications for the components are adopted. We derived the spectral types of the system GSC 2750-0054 as K3 and K7. The physical parameters of the system are M1 = 0.72 ± 0.03 Mâ, M2 = 0.47 ± 0.02 Mâ, R1 = 0.81 ± 0.03 Râ, R2 = 0.62 ± 0.03 Râ, L1 = 0.27 ± 0.01 Lâ and L2 = 0.1 ± 0.004 Lâ. For the system, GSC 03208 02644 the spectral types of the components are A5 and A8. The physical parameters are M1 = 1.86 ± 0.076 Mâ, M2 = 1.21 ± 0.049 Mâ, R1 = 1.84 ± 0.075 Râ, R2 = 1.75 ± 0.072 Râ, L1 = 13.58 ± 0.55 Lâ and L2 = 9.94 ± 0.41 Lâ. Comparison with the evolutionary models as well as the empirical databases is presented.
