Radial temperature profiles of three typical bubbles of the WR100V05 simulation. From top to bottom, the models represent case 1 (T_eff = 44 000 K), case 2 (T_eff = 56 000 K), and case 3 (T_eff = 80 000 K, with beginning evaporation). The central star is at r = 0 cm. The vertical dashed lines mark the transition from the hydrogen-poor WR (left) to the hydrogen-rich PN chemistry (right). The bubble parameters like characteristic X-ray-temperatures, X-ray luminosities, and masses (for the entire bubble and for the respective subregions with the WR or PN composition) are given in the legends. The symbols on the bubble’s temperature profile mark different characteristic temperatures: of the entire bubble (diamond), the hydrogen-poor part only (star), and the hydrogen-rich evaporated part only (plus).
