    • 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, ...

    • Heavy elements and age determinations 

      Thielemann, Friedrich-Karl; Hauser, P.; Kolbe, E.; Martinez-Pinedo, Gabriel; Panov, I.; Rauscher, T.; Kratz, K.L.; Pfeiffer, B.; Rosswog, S.; Liebendoerfer, M.; Mezzacappa, A. (2002-01)
      The age of the universe, measured from the Big Bang to the present, is at the focus of cosmology. Its determination relies, however, on the use of stellar objects or their products. Stellar explosions, like type Ia supernovae ...

    • The importance of parity-dependence of the nuclear level density in the prediction of astrophysical reaction rates 

      Mocelj, D.; Rauscher, T.; Martinez-Pinedo, Gabriel; Alhassid, Y. (World Scientific Publishing, 2003)
      A simple description for obtaining the parity distribution of nuclear levels in the pf + g(9/2) shell as a function of excitation energy was recently derived. We implement this in a global nuclear level density model. In ...

    • Nucleosynthesis in core-collapse supernova explosions triggered by a quark-hadron phase transition 

      Nishimura, Nobuya; Fischer, Tobias; Thielemann, Friedrich-Karl; Froehlich, Carla; Hempel, Matthias; Kaeppeli, Roger; Martinez-Pinedo, Gabriel; Rauscher, T.; Sagert, Irina; Winteler, Christian (2012-10-10)
      We explore heavy-element nucleosynthesis in the explosion of massive stars that are triggered by a quark-hadron phase transition during the early post-bounce phase of core-collapse supernovae. The present study is based ...

    • 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 : Supernovae and other sources of the heaviest elements 

      Thielemann, Friedrich-Karl; Mocelj, D.; Panov, I.; Kolbe, E.; Rauscher, T.; Kratz, K.L.; Farouqi, K.; Pfeiffer, B.; Martinez-Pinedo, Gabriel; Kelic, A.; Langanke, K.; Schmidt, K. -H.; Zinner, N. (2007-05)
      Rapid neutron capture in stellar explosions is responsible for the heaviest elements in nature, up to Th, U and beyond. This nucleosynthesis process, the r-process, is unique in the sense that a combination of nuclear ...
