Early galactic heavy element production - a phenomenological approach
B. Wehmeyer, D. Blaschke, F. K. Röpke +1
The high abundances of heavy elements in early, extremely metal-poor stars is still an unsolved issue in Galactic Chemical Evolution (GCE). Standard approaches, such as mergers of…
Inhomogeneous enrichment of radioactive nuclei in the Galaxy: Deposition of live Mn-53, Fe-60, Hf-182, and Pu-244 into deep-sea archives. Surfing the wave?
Benjamin Wehmeyer, Andrés Yagüe López, Benoit Côté +3
While modelling the galactic chemical evolution (GCE) of stable elements provides insights to the formation history of the Galaxy and the relative contributions of nucleosynthesis…
Using failed supernovae to constrain the Galactic r-process element production
B. Wehmeyer, C. Frohlich, B. Côté +2
Rapid neutron capture process (r-process) elements have been detected in a large fraction of metal-poor halo stars, with abundances relative to iron (Fe) that vary by over two orde…
Advanced LIGO Constraints on Neutron Star Mergers and R-Process Sites
Benoit Côté, Krzysztof Belczynski, Chris L. Fryer +4
The role of compact binary mergers as the main production site of r-process elements is investigated by combining stellar abundances of Eu observed in the Milky Way, galactic chemi…
Galactic evolution of rapid neutron capture process abundances: the inhomogeneous approach
B. Wehmeyer, M. Pignatari, F. -K. Thielemann
For the origin of heavy r-process elements, different sources have been proposed, e.g., core-collapse supernovae or neutron star mergers. Old metal-poor stars carry the signature o…
