Table A.2.

MESA models description, using the options defined in Table A.1. Both MSCZ and TBSCZ are defined using the highest position of the SCZ in the stars, in order to avoid the issue described in Sect. A.1. The value for option 3 of the model A3 (default value) makes it so that only standard opacity tables are used.

Notes.

a

Due to the value order presented in Table 2, the options 5 and 6 were also set to their default values.

b

As log10(Tcore) = 7.25, the A32 model takes monochromatic opacities into account in the whole interior in this case.

c

Mean surface abundance difference in mass fraction over all elements, relative to A0.

d

Maximum surface abundance difference over all elements, relative to A0 (see Fig. D.1).
