Bayesian Inference of Stellar r-Process Abundances
Jan Kuske, Almudena Arcones, Isak Svensson
The abundances of heavy elements observed in metal-poor, r-process-enhanced stars provide unique information about the astrophysical conditions in which the rapid neutron-capture p…
HRMOS: A High-Resolution Multi-Object Spectrograph for the VLT
Laura Magrini, Thomas Bensby, Sofia Randich +174
This White Paper presents the scientific rationale and instrument concept for HRMOS (High-Resolution Multi-Object Spectrograph), a next-generation instrument proposed for the ESO V…
r-Process Nucleosynthesis With Ab Initio Nuclear Masses Around The N=82 Shell Closure
Jan Kuske, Takayuki Miyagi, Almudena Arcones +1
Our understanding of the origin of heavy elements beyond iron relies on the rapid neutron capture process (r-process), which accounts for roughly half of their cosmic abundance. Ho…
Propagating Uncertainties from Nuclear Physics to Gamma-rays in Core Collapse Supernovae
Chris L Fryer, Hendrik Schatz, Samuel Jones +18
Nuclear yields are powerful probes of supernova explosions, their engines and their progenitors. In addition, as we improve our understanding of these explosions, we can use nuclea…
Constraining r-process nucleosynthesis with multi-objective Galactic chemical evolution models
M. Molero, A. Arcones, F. Montes +1
The astrophysical site(s) of the r-process are uncertain, with candidates such as neutron star mergers and magneto-rotational supernovae predicting different event rates, delay tim…
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…
