We provide here a significant extension of the NuGrid Set 1 models in mass coverage and toward lower metallicity , adopting the same physics assumptions .
The combined data set now includes the initial masses M _ { ZAMS } / { M } _ { \odot } = 1 , 1.65 , 2 , 3 , 4 , 5 , 6 , 7 , 12 , 15 , 20 , 25 for Z = 0.02 , 0.01 , 0.006 , 0.001 , 0.0001 with \alpha -enhanced composition for the lowest three metallicities .
These models are computed with the MESA stellar evolution code and are evolved up to the AGB , the white dwarf stage , or until core collapse .
The nucleosynthesis was calculated for all isotopes in post-processing with the NuGrid mppnp code .
Explosive nucleosynthesis is based on semi-analytic 1D shock models .
Metallicity-dependent mass loss , convective boundary mixing in low- and intermediate mass models and H and He core burning massive star models is included .
Convective O-C shell mergers in some stellar models lead to the strong production of odd-Z elements P , Cl , K and Sc .
In AGB models with hot dredge-up the convective boundary mixing efficiency is reduced to accommodate for its energetic feedback .
In both low-mass and massive star models at the lowest metallicity H-ingestion events are observed and lead to i-process nucleosynthesis and substantial ^ { \makebox [ 14.999771 pt ] [ r ] { $ \scriptstyle 15 $ } } _ { \makebox [ 14.999771 pt ] [ r ] { $% \scriptstyle$ } } \mathrm { N } production .
Complete yield data tables , derived data products and online analytic data access are provided .
