Fraction of light elements that are produced by which nucleosynthetic channel when the Chempy parameters are constrained by the Sun+ observations. The fractional yield of CC-SN, SN Ia, and AGB is shown in blue, green, and red, respectively (in solid for the maximum posterior parameters and transparently for 100 results from the converged MCMC). The upper (lower) panel shows the result using the default (alternative) yield set. The bars in the middle panel indicate each element’s contribution to the total net yield (for the maximum posterior of the default yield set, for comparison, the prior feedback contribution is given in black lines but the difference is hardly visible on the log scale). The results from parameters are shown as black lines. These are best suited when looking for differences in the yield sets because the colored lines coming from θ_posterior are superimposed with the effect of having different Chempy parameters. It is important to note that the CC-SN yield of the alternative yield set (Chieffi & Limongi 2004) is gross, not net yield. Therefore the feedback includes unprocessed solar scaled material.
