    • Chemodynamical evolution of the Milky Way 

      Kobayashi, C.; Nakasato, N.; Nomoto, K. (Astronomical Society of the Pacific, 2003)
      We simulate the chemodynamical evolution of the Milky Way using our GRAPE-SPH code, and reproduce the age-metallicity relation, the [O/Fe]-[Fe/H] relation, and the metallicity distribution.

    • Element synthesis in stars 

      Thielemann, Friedrich-Karl; Brachwitz, F.; Freiburghaus, C.; Kolbe, E.; Martinez-Pinedo, Gabriel; Rauscher, T.; Rembges, F.; Hix, W. R.; Liebendoerfer, M.; Mezzacappa, A.; Kratz, K.L.; Pfeiffer, B.; Langanke, K.; Nomoto, K.; Rosswog, S.; Schatz, H.; Wiescher, Michael (Elsevier, 2001)
      Except for H-1, H-2, He-3, He-4, and Li-7, originating from the Big Bang, all heavier elements are made in stellar evolution and stellar explosions. Nuclear physics, and in many cases nuclear structure far from stability, ...

    • Lifetime of Type Ia Supernovae and chemical evolution of Galaxies 

      Kobayashi, C.; Nomoto, K. (2003-05-05)

    • The new record holder for the most iron-poor star: HE 1327−2326, a dwarf or subgiant with [Fe/H] = −5.4 

      Frebel, A.; Aoki, W.; Christlieb, N.; Ando, H.; Asplund, M.; Barklem, P.S.; Beers, T.C.; Eriksson, K.; Fechner, C.; Fujimoto, M.Y.; Honda, S.; Kajino, T.; Minezaki, T.; Nomoto, K.; Norris, J.E.; Ryan, Sean G.; Takada-Hidai, M.; Tsangarides, S.; Yoshii, Y. (2005)
      We describe the discovery of HE 1327−2326, a dwarf or subgiant with [Fe/H] = −5.4. The star was found in a sample of bright metal-poor stars selected from the Hamburg/ESO survey. Its abundance pattern is characterized by ...

    • Nucleosynthesis and stellar evolution 

      Thielemann, Friedrich-Karl; Argast, D.; Brachwitz, F.; Martinez-Pinedo, G.; Rauscher, T.; Liebendoerfer, M.; Mezzacappa, A.; Hoflich, P.; Nomoto, K. (2002)
      Two of the basic building blocks of galaxies are stars and the interstellar medium. The evolution of the abundance composition in the latter and especially the enrichment of heavy elements as a function of space and time ...

    • Nucleosynthesis in supernovae 

      Thielemann, Friedrich-Karl; Argast, D.; Brachwitz, F.; Martinez-Pinedo, Gabriel; Rauscher, T.; Liebendoerfer, M.; Mezzacappa, A.; Hoflich, P.; Iwamoto, K.; Nomoto, K. (Astronomical Society of the Pacific, 2002)
      The evolution of gas abundances in galaxies and the enrichment of heavy elements as a function of space and time reflects the history of star formation and the lifetimes of the diverse contributing stellar objects. Supernovae ...

    • Nucleosynthetic signatures of the first stars 

      Frebel, A.; Aoki, W.; Christlieb, N.; Ando, H.; Asplund, M.; Barklem, P.S.; Beers, T.C.; Eriksson, K.; Fechner, C.; Fujimoto, M.Y.; Honda, S.; Kajino, T.; Minezaki, T.; Nomoto, K.; Norris, J.E.; Ryan, Sean G.; Takada-Hidai, M.; Tsangarides, S.; Yoshii, Y. (2005-04)

    • Proton-rich nucleosynthesis and nuclear physics 

      Rauscher, T.; Froehlich, C. (American Institute of Physics (AIP), 2012)
      Although the detailed conditions for explosive nucleosynthesis are derived from astrophysical modeling, nuclear physics determines fundamental patterns in abundance yields, not only for equilibrium processes. Focussing on ...

    • Spectroscopic studies of extremely metal-poor stars with the Subaru high dispersion spectrograph. IV : The alpha-element-enhanced metal-poor star BS16934-002 

      Aoki, W.; Honda, S.; Beers, T.C.; Takada-Hidai, M.; Iwamoto, N.; Tominaga, N.; Umeda, H.; Nomoto, K.; Norris, J.E.; Ryan, Sean G. (2007)

    • Type Ia supernovae : Progenitors and diversities 

      Nomoto, K.; Uenishi, T.; Kobayashi, C.; Umeda, H.; Ohkubo, T.; Hachisu, I.; Kato, M. (Springer Nature, 2003)
      A key question for supernova cosmology is whether the peak luminosities of Type Ia supernovae (SNe Ia) are sufficiently free from the effects of cosmic and galactic evolution. To answer this question, we review the currently ...
