Left column: density structure vs. radius (top) and mass (middle) for the model set of H-rich progenitors. The composition for the main species is shown in the bottom panel. The composition profiles are shown for all H-rich models in Fig. A.1. All these MESA models are evolved until iron core collapse. Right column: same as left column, but for the properties of the He-giant progenitor model He_R173. This He-giant model is evolved only until the onset of core neon burning. The colour-coding used for the composition (bottom row) differs for H-rich (left) and H-deficient models (right).
