| contents | In this study, we applied Al-Wardat's method to analyze the subgiant system HIP72217 for which we obtained accurate parameters including stellar masses, effective temperatures ($T_{\text{eff}}$) and system age.For the primary component we determined a stellar mass of $M_A = 1.14 \pm 0.15\,M_{\odot}$ and effective temperature $T_{\text{eff,A}} = 6125 \pm 50$\,K while for the secondary component we obtained the values of $M_B = 1.12 \pm 0.14\,M_{\odot}$ and $T_{\text{eff,2}} = 5950 \pm 50$\,K. The system's age was estimated to be $3.548 Gyr$, which is consistent with the predicted evolutionary period of a subgiant binary. The evolutionary timeline of HIP\,72217 becomes clearer through our study, which also demonstrates Al-Wardat's approach as an effective approach for binary star system characterization. These findings contribute to a better understanding of the physical mechanisms that control subgiant binary evolution and their broader role in stellar evolutionary processes. |
