Nucleosynthesis in the fast ejecta of a neutron star merger
Lukas Schnabel, Stephan Rosswog, Friedrich-Karl Thielemann +1
Neutron star mergers are today considered a major production site for rapid neutron capture elements. While the bulk of the matter escapes at fast, but non-relativistic velocities…
The r-Process: History, Required Conditions, Astrophysical Sites, and Observations
Friedrich-Karl Thielemann, John J. Cowan
This review of the rapid-neutron-capture (i.e. r-) process starts with determining the Solar System r-abundance pattern via first obtaining (and subtracting) the contribution from…
Deciphering the Origins of the Elements Through Galactic Archeology
Khalil Farouqi, Anna Frebel, Friedrich-Karl Thielemann
Low-metallicity stars preserve the signatures of the first stellar nucleosynthesis events in the Galaxy, as their surface abundances reflect the composition of the interstellar med…
Do not forget the electrons: Extending moderately-sized nuclear networks for multidimensional hydrodynamic codes
Domingo GarcÃa-Senz, Rubén M. Cabezón, Moritz Reichert +5
We present here an extended nuclear network, with 90 species, designed for being coupled with hydrodynamic simulations, which includes neutrons, protons, electrons, positrons, and…
