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 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 ... -
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 Impact of Fission on R-Process Calculations
Eichler, M.; Arcones, A.; Käppeli, R.; Korobkin, O.; Liebendörfer, M.; Martinez-Pinedo, G.; Panov, I. V.; Rauscher, T.; Rosswog, S.; Thielemann, F. K.; Winteler, C. (2016-01-05)We have performed r-process calculations in neutron star mergers (NSM) and jets of magnetohydrodynamically driven (MHD) supernovae. In these very neutron-rich environments the fission model of heavy nuclei has an impact ... -
Nuclear physics issues of the r-process
Thielemann, Friedrich-Karl; Kolbe, E.; Martinez-Pinedo, G.; Panov, I.; Rauscher, T.; Kratz, K.L.; Pfeiffer, B.; Rosswog, S. (World Scientific Publishing, 2003)The present paper aims at understanding r-process nucleosynthesis by addressing the nuclear physics involved, the necessary environment conditions in the (stellar) production sites, and the observational constraints. We ... -
The Role of Fission in Neutron Star Mergers and Its Impact on the r-Process Peaks
Eichler, M.; Arcones, A.; Kelic, A.; Korobkin, O.; Langanke, K.; Marketin, T.; Martinez-Pinedo, G.; Panov, I.; Rauscher, T.; Rosswog, S.; Winteler, C.; Zinner, N. T.; Thielemann, F. K. (2015-07-15)Comparing observational abundance features with nucleosynthesis predictions of stellar evolution or explosion simulations, we can scrutinize two aspects: (a) the conditions in the astrophysical production site and (b) the ... -
The role of fission on neutron star mergers and its impact on the r-process peaks
Eichler, M.; Arcones, A.; Kelic, A.; Korobkin, O.; Langanke, K.; Marketin, T.; Martinez-Pinedo, G.; Panov, I.; Rauscher, T.; Rosswog, S.; Winteler, C.; Zinner, N. T.; Thielemann, F. K. (American Institute of Physics (AIP), 2016-06-21)The comparison between observational abundance features and those obtained from nucleosynthesis predictions of stellar evolution and/or explosion simulations can scrutinize two aspects: (a) the conditions in the astrophysical ...
