    Evidence for p-process nucleosynthesis recorded at the Solar System abundances

    Analyzing the Solar System abundance, we have found two universal scaling laws concerning the p- and s-nuclei with the same atomic number. They are evidence of the p-nucleus origin that has been discussed for ...

    Nucleosynthesis in Black-Hole-Forming Supernovae

    Stars more massive than ∼ 20 − 25 M form a black hole at the end of their evolution. Stars with non-rotating black holes are likely to collapse “quietly” ejecting a small amount of heavy elements (faint supernov...

    Yields from Type Ia Supernovae

    Supernovae of both types represent the most important nucleosynthesis contributors to galactic evolution and SNe la represent the major source of Fe-group nuclei. Our theoretical understanding is still burdene...

    Nucleosynthesis in Type II Supernovae and Abundance Trends of Iron-Peak Elements in Metal-Poor Stars

    Recent high-resolution abundance surveys show interesting trends of [Cr/Fe], [Mn/Fe], and [Co/Fe] with [Fe/H]. Both [Cr/Fe] and [Mn/Fe] decrease as metallicity declines from [Fe/H] = −2.4 to −4.0, while [Co/Fe...
