    • Mg abundances in metal-poor halo stars as a tracer of early Galactic mixing 

      Arnone, E.; Ryan, Sean G.; Argast, D.; Norris, J.E.; Beers, T.C. (2005-02)

    • Nuclear cross sections, nuclear structure and stellar nucleosynthesis 

      Thielemann, Friedrich-Karl; Argast, D.; Brachwitz, F.; Hix, W. R.; Hoflich, P.; Liebendoerfer, M.; Martinez-Pinedo, G.; Mezzacappa, A.; Panov, I.; Rauscher, T. (2003-05-05)
      The role of nuclear reactions (strong, weak and electromagnetic) and nuclear structure effects are discussed in a number of stellar applications. We address fusion cross sections in stellar evolution, neutrino-induced ...

    • Nuclear physics : A key ingredient in astrophysical modeling 

      Thielemann, Friedrich-Karl; Argast, D.; Brachwitz, F.; Fisker, J. L.; Froehlich, Carla; Hirschi, R.; Kolbe, E.; Mocelj, D.; Rauscher, T. (2005-04-18)
      Nuclear physics is a basic ingredient in a large number of energetic astrophysical environments which are characterized by sufficient temperatures and densities to permit scattering events among particles, leading to nuclear ...

    • 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 ...

    • The r-process in supernovae 

      Thielemann, Friedrich-Karl; Argast, D.; Mocelj, D.; Rauscher, T.; Cowan, J.J.; Kratz, K.L.; Pfeiffer, B. (World Scientific Publishing, 2004-09)
      This introductory review aims at understanding r-process nucleosynthesis by addressing the issues involved, nuclear properties, necessary environment conditions, properties of different suggested r-process sites, observational ...
