This binary has a circular orbit, an orbital period of 1.2 days, and contains two stars of almost identical masses ($M_1=1.72M_{\\odot}, M_2=1.71M_{\\odot}$). However, the cooler secondary star is more evolved ($R_2=1.96R_{\\odot}$) while the hotter primary is still on the zero-age-main-sequence ($R_1=1.53R_{\\odot}$). Coeval models from single star evolution cannot explain the observed masses and radii, and binary evolution with mass-transfer needs to be invoked.
