Abstract Model atmospheres of the components of the visually close binary system Hip 11352 were constructed using a grid of Kurucz's blanketed models. The entire observational spectral energy distribution of the system was used as a reference for the comparison with synthetic ones created from the model atmospheres. The parameters of the components of the system were derived as T eff a = 5650 ± 50 K, T eff b = 5550 ± 50 K, log g a = 4.47 ± 0.13, log g b = 4.49 ± 0.13, R a = 0.92 ± 0.03 R ⊙ , R b = 0.88 ± 0.02 R ⊙ , M a = 0.93 ± 0.05 M ⊙ , M b = 0.89 ± 0.05 M ⊙ , with a spectral type G7 for the primary and G9 for the secondary. The synthetic magnitudes and of both components were calculated using Johnson‐Cousins, Strömgren, and Tycho photometrical systems. Finally the formation and evolution of the system was discussed (© 2009 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
