The new photometric solution and light curve study of the semi-detached binary system ASAS ID 211049-3657.9

•We present the new photometric solution of the ASAS ID 211049-3657.9.•We demonstrated that ASAS ID 211049-3657.9 should be an semi-detached binaries.•We present that the secondary component is the spotted and the magneticaly star.•We proposed the possible evolutionary statue.•The distance of the system was calculated as d=220.942pc. This work is targeted on the photometric (light curve) analysis of the stars with G2 spectral type. The sun like star (ASAS ID 211049-3657.9) located in the ASAS catalogue was subjected to its photometric solutions and the light curve analysis in V band. The light curve of ASAS ID 211049-3657.9 binary system which belongs to the Southern Hemisphere shows the variation of β Lyr type. The solution of light curve was carried out using the PHOBE code. The photometric solution reveals a semi-detached configuration with a less-massive component filling its own Roche lobe. The absolute parameters, very close to the astrophysical fundamental values of the sun, are obtained as a result of the solution. A spotted solution for ASAS ID 211049-3657.9 binary system with the Sun-like selected from the solar analogue star list of Tanrıver (2012, 2013) is conducted. The masses of the primary and secondary components for ASAS ID 211049-3657.9 are M1=1.00741M⊙ and M2=0.37535M⊙, respectively. While the radius for the primary was R1=1.00097R⊙, and for the secondary R2=1.19107R⊙ and the temperature of the primary and secondary are T1=5850K and T2=5150K, respectively. The positions in the HR diagram of the components are also discussed.
