    • An approximation for the rp-process 

      Rembges, F.; Freiburghaus, C.; Rauscher, T.; Thielemann, F.K.; Schatz, H.; Wiescher, M. (1997-07-20)
      Hot (explosive) hydrogen burning, or the rapid proton capture process (rp-process), occurs in a number of astrophysical environments. Novae and X-ray bursts are the most prominent ones, but accretion disks around black ...
    • Astrophysical and nuclear physics aspects of the r-process 

      Thielemann, Friedrich-Karl; Freiburghaus, C.; Rauscher, T.; Kratz, K.L.; Pfeiffer, B.; Cowan, J.J. (World Scientific Publishing, 1998)
      The formation of elements as heavy as Th and U and beyond is due to the rapid neutron-capture process (r-process), which causes the production of highly unstable nuclei near the neutron drip-line and functions via neutron ...
    • Astrophysical conditions for an r-process in the high-entropy wind scenario of type II supernovae 

      Farouqi, K.; Freiburghaus, C.; Kratz, K. L.; Pfeiffer, B.; Rauscher, T.; Thielemann, Friedrich-Karl (2005-07-25)
      Within a full dynamical parameter study including freezeout effects, we have determined the astrophysical conditions for an r-process in the so-called "neutrino-wind" scenario of core-collapse type II supernovae (SNII). ...
    • The astrophysical r-process : A comparison of calculations following adiabatic expansion with classical calculations based on neutron densities and temperatures 

      Freiburghaus, C.; Rembges, J.F.; Rauscher, T.; Kolbe, E.; Thielemann, Friedrich-Karl; Kratz, K.L.; Pfeiffer, B.; Cowan, J.J. (1999-05-01)
      The rapid neutron-capture process (r-process) encounters unstable nuclei far from beta-stability. Therefore its observable features, like the abundances, witness (still uncertain) nuclear structure as well as the conditions ...
    • 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, ...
    • Explosive nucleosynthesis and the astrophysical r-process 

      Thielemann, Friedrich-Karl; Freiburghaus, C.; Rauscher, T.; Kolbe, E.; Pfeiffer, B.; Kratz, K.L.; Cowan, J.J. (American Institute of Physics (AIP), 1998)
      We give an overview of chemical equilibria in explosive burning and the role which neutron and/or proton separation energies play. We focus then on the rapid neutron-capture process (r-process) which encounters unstable ...
    • Explosive nucleosynthesis close to the drip lines 

      Thielemann, Friedrich-Karl; Freiburghaus, C.; Rauscher, T.; Rembges, F.; Rosswog, S.; Pfeiffer, B.; Kratz, K.L.; Schatz, H.; Wiescher, M. (1998-11)
      We give an overview of explosive burning and the role which neutron and/or proton separation energies play. We focus then on the rapid neutron capture process (r-process) which encounters unstable nuclei with neutron ...
    • The r-process in the high entropy bubble 

      Freiburghaus, C.; Rauscher, T.; Thielemann, Friedrich-Karl; Kratz, K.L.; Pfeiffer, B. (1997-08-04)
