Mass fraction of central abundances for a rotating 15 M_⊙ from He-burning to O-burning, shown for the three nuclear models: CF88, HIN(RES), and TDHF (line-coded). For comparison, a CF88 model using the rates from Kunz et al. (2002) is shown in dotted lines. Shaded areas show the successive nuclear burning phases with colours corresponding to He-, C-, Ne-, and O-burning (grey, red, green, and blue, respectively).
