Complete survey of r-process conditions: the (un-)robustness of the r-process(-es)
Jan Kuske, Almudena Arcones, Moritz Reichert
Heavy elements are synthesized by the r-process in neutron star mergers and potentially in rare supernovae linked to strong magnetic fields. Expensive hydrodynamic simulations of t…
Evolving massive stars to core collapse with GENEC: Extension of equation of state, opacities and effective nuclear network
Adam Griffiths, Miguel-Ã Aloy, Raphael Hirschi +6
Stars with initial mass above roughly 8 solar masses will evolve to form a core made of iron group elements at which point no further exothermic nuclear reactions between charged n…
Chemical Evolution of R-process Elements in Stars (CERES): IV. An observational run-up of the third r-process peak with Hf, Os, Ir, and Pt
Arthur Alencastro Puls, Jan Kuske, Camilla Juul Hansen +8
The third r-process peak (Os, Ir, Pt) is poorly understood due to observational challenges, with spectral lines located in the blue or near-ultraviolet region of stellar spectra. T…
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…
