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…
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…
Evolving massive stars to core collapse with GENEC: Extension of equation of state, opacities and effective nuclear network
Adam Griffiths, Miguel-Á 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…
Do not forget the electrons: Extending moderately-sized nuclear networks for multidimensional hydrodynamic codes
Domingo García-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…
Nucleosynthesis in magnetorotational supernovae: impact of the magnetic field configuration
M. Reichert, M. Bugli, J. Guilet +3
The production of heavy elements is one of the main by-products of the explosive end of massive stars. A long sought goal is finding differentiated patterns in the nucleosynthesis…
The nuclear reaction network WinNet
M. Reichert, C. Winteler, O. Korobkin +13
We present the state-of-the-art single-zone nuclear reaction network WinNet that is capable of calculating the nucleosynthetic yields of a large variety of astrophysical environmen…
Nucleosynthesis in jet-driven and jet-associated supernovae
M. Obergaulinger, M. Reichert
In contrast to regular core-collapse supernovae, explosions of rapidly rotating massive stars can develop jets, fast collimated outflows directed along the rotational axis. Dependi…
Core-collapse supernova simulations with reduced nucleosynthesis networks
Gerard Navó, Moritz Reichert, Martin Obergaulinger +1
We present core-collapse supernova simulations including nuclear reaction networks that impact explosion dynamics and nucleosynthesis. The different composition treatment can lead…
Chemical Evolution of R-process Elements in Stars (CERES). I. Stellar parameters and chemical abundances from Na to Zr
Linda Lombardo, Piercarlo Bonifacio, Patrick François +10
Aims. The Chemical Evolution of R-process Elements in Stars (CERES) project aims to provide a homogeneous analysis of a sample of metal-poor stars ([Fe/H]<-1.5). We present the ste…
Magnetorotational supernovae: A nucleosynthetic analysis of sophisticated 3D models
Moritz Reichert, Martin Obergaulinger, Miguel-Angel Aloy +3
Magnetorotational supernovae are a rare type of core-collapse supernovae where the magnetic field and rotation play a central role in the dynamics of the explosion. We present the…
Post-explosion evolution of core-collapse supernovae
M. Witt, A. Psaltis, H. Yasin +6
We investigate the post-explosion phase in core-collapse supernovae with 2D hydrodynamical simulations and a simple neutrino treatment. The latter allows us to perform 46 simulatio…
Evolution of neutron capture elements in dwarf galaxies
Marta Molero, Donatella Romano, Moritz Reichert +6
We study the evolution of Eu and Ba abundances in local group dwarf spheroidal and ultra faint dwarf galaxies by means of detailed chemical evolution models and compare our results…
Extreme r-process enhanced stars at high metallicity in Fornax
M. Reichert, C. J. Hansen, A. Arcones
We present and discuss three extremely r-process enhanced stars located in the massive dwarf spheriodal galaxy Fornax. These stars are very unique with an extreme Eu enrichment ($1…
Nucleosynthesis in magneto-rotational supernovae
Moritz Reichert, Martin Obergaulinger, Marius Eichler +2
We present the nucleosynthesis of magneto-rotational supernovae (MR-SNe) including neutrino-driven and magneto-rotational-driven ejecta based, for the first time, on 2D simulations…
An empirical metallicity tracer in CEMP and C-normal stars
D. Singh, C. J. Hansen, J. S. Byrgesen +2
Deriving the metallicity, [Fe/H], in low-resolution spectra of carbon-enhanced metal-poor (CEMP) stars is a tedious task that, owing to the large number of line blends, often leads…
Unusual neutron-capture nucleosynthesis in a carbon-rich Galactic bulge star
A. Koch, M. Reichert, C. J. Hansen +4
Metal-poor stars in the Galactic halo often show strong enhancements in carbon and/or neutron-capture elements. However, the Galactic bulge is notable for its paucity of carbon-enh…
Neutron Star Mergers Might not be the Only Source of r-Process Elements in the Milky Way
Benoit Côté, Marius Eichler, Almudena Arcones +8
Probing the origin of r-process elements in the universe represents a multi-disciplinary challenge. We review the observational evidence that probe the properties of r-process site…
