Temperature profiles at different stages of the evolution (blue lines) and maximum temperature reached during the explosion (magenta line) for the M25Zm3V4 model. The abundance profile of the s-nuclide ⁸⁸Sr is shown in black with the scale on the right. The blue and magenta rectangle show where the p-process can take place (in terms of temperature range and mass coordinate range) during the hydrostatic and explosive burning, respectively (see text for details). The dark grey area shows the extent of the remnant (corresponding to the size of the ⁵⁶Ni core; cf. Sect. 2.2). The three horizontal dashed lines correspond to temperatures of 1.5, 1.8, and 3.7 GK.
