Kippenhahn diagram of a 4.0 M_⊙ star with Z = 0.02 from the main sequence to the end of the thermally pulsing AGB from Miller Bertolami (2016). The hatched green and blue areas indicate the central and outer convective zones, respectively. The orange and purple lines indicate the outer limits of the H- and He-depleted regions, respectively. The pink shaded area is the region where the magnetic fields are expected to be buried. The intershell convective zones driven by the thermal pulses on the AGB are not visible in this plot. The final WD mass of this model is 0.83 M_⊙.
