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…
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…
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…
