Cumulative net yield in M_⊙ for C, N, O and Fe over time for an SSP of 1 M_⊙ and solar metallicity Z_⊙, using Chempy’s parameters (see Table 1). The nucleosynthetic enrichment of CC-SN in blue, SN Ia in green, and AGB in red are plotted. We show the default yield set in solid lines and for the alternative yield set in dashed lines (those are defined in Table 2). Linear time steps of 9.6 Myr (in contrast to the fiducial Δt = 0.1 Gyr) are indicated by the short vertical lines at the top together with the mass of stars dying at that time. We note that for the alternative CC-SN yield only gross yields are available (unprocessed material is included in the feedback, see text).
