Light curves for the same outburst model as in Figs. 2 and 5, computed assuming that the accreted matter fills the crust to the density ρ_acc = 10¹³ g cm⁻³ for a neutron star with mass M = 1.4 M_⊙, using the EoS models BSk24 (solid and short-dashed lines) and BSk25 (dot-dashed and long-dashed lines). The non-accreted part of the crust is assumed either pure (solid and dot-dashed lines) or with the frozen equilibrium mixture (short- and long-dashed lines). The F+18 model is adopted for the accreted crust composition and heating. The inset shows the cooling part of the same light curves in the logarithmic scale.
