- Kobayashi led the theoretical interpretation of the most metal-poor star in the Galactic bulge discovered by the Australian SkyMapper telescope and created Figure 3 of this Nature paper. As the only theorist in nucleosynthesis among the authors, in order to explain the observed elemental abundances from C to Zn Kobayashi provided two models of core-collapse supernovae, and another model of a pair-instability supernova, which led to one of the main conclusions of the paper: the first chemical enrichment of the Universe is likely to be driven by core-collapse supernovae rather than pair-instability supernovae, contrary to the conclusion of previous papers.
