129I and 247Cm in Meteorites Constrain the Last Astrophysical Source of Solar r-process Elements
Benoit Côté, Marius Eichler, Andrés Yagüe +12
The composition of the early Solar System can be inferred from meteorites. Many elements heavier than iron were formed by the rapid neutron-capture process (r process), but the ast…
Origin of Plutonium-244 in the Early Solar System
Maria Lugaro, Andrés Yagüe López, Benjámin Soós +5
We investigate the origin in the early Solar System of the short-lived radionuclide 244Pu (with a half life of 80 Myr) produced by the rapid (r) neutron-capture process. We conside…
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 chemical evolution with the short-lived isotopes Mn-53, Fe-60, Hf-182, and Pu-244
Benjamin Wehmeyer, Andrés Yagüe López, Benoit Côté +3
We run a three-dimensional Galactic chemical evolution (GCE) model to follow the propagation of Mn-53 from supernovae of type Ia (SNIa), Fe-60 from core-collapse supernovae (CCSNe)…
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…
The Radioactive Nuclei Al and Fe in the Cosmos and in the Solar System
Roland Diehl, Maria Lugaro, Alexander Heger +15
The cosmic evolution of the chemical elements from the Big Bang to the present time is driven by nuclear fusion reactions inside stars and stellar explosions. A cycle of matter rec…
Core-collapse Supernova Explosions Driven by the Hadron-quark Phase Transition as a Rare -process Site
Tobias Fischer, Meng-Ru Wu, Benjamin Wehmeyer +3
Supernova explosions of massive stars are one of the primary sites for the production of the elements in the universe. Up to now, stars with zero-age main-sequence masses in the ra…
