Left panel: redshifted effective temperature vs. time for the neutron star models with different EOS and masses. The solid, dashed, and dot-dashed curves correspond to the neutron stars of 1.4, 1.6, and 2.0 M_⊙, respectively, with the BHF EOS. The dot-dot-dashed line represents 2 M_⊙ neutron star with the EOS of APR. Central panel: fit of the Cas A data with the BHF EOS for a neutron star of 1.4M_⊙ and a turbulent magnetic field of initial strength 2.2 × 10¹³ G. Right panel: fit of the Cas A data with the APR EOS for a neutron star of 2.0M_⊙ and a turbulent magnetic field of initial strength 9.5 × 10¹² G.
