Redshifted temperature as function of mass density at one week and one, three, and ten years after the outburst for the same models of the crust as in Fig. 5. The redshifted temperature in the core is fixed at K. The long vertical dotted lines mark the boundaries of the crust with the envelope and the core. The shorter vertical dotted line marks the interface between the accreted and ground-state matter in the models of partially accreted envelope.
