2018 model grid · interactive tool
Isotope & element production across the grid
Choose an isotope or an element and see how much of it is produced as a function of the initial mass, [Fe/H] and rotation velocity, and in which hydrostatic or explosive burning zones. For a single model, see the isotope origin explorer.

Notes
Net yield = total yield − initial amount in the ejecta, (Mini − Mcut) × Xini; it is shown only where positive (a net destruction cannot be plotted in logarithmic scale). The production factor is the ratio of the total yield to the initial amount in the ejecta. For an element the isotopes are summed. Zone percentages come from the same attribution as the isotope origin explorer (a port of the logic of
prosit.f90); for an element they are weighted by the yields of its produced isotopes. Zones: wind, H burning, He shell (Hesh), He core (Hec), C shell (Csh), Ne shell (Nsh), O shell (Osh), explosive C/Ne (CNex), explosive O (Ox), incomplete (Siix) and complete (Six) explosive Si burning. Sets F/I/M/R are those of the 2018 yields (see the explorer for their definition); in sets I and R, models above 25 M☉ eject only the wind (100% wind). The explosive zones are credited only with the net excess over the pre-explosive abundance. Models without an exploded profile are missing in sets F and M. The data are precomputed in isotope_origin_grid_F/I/M/R.json by build_origin_grid.js; use the explorer for a user-defined set.
