Representation of s-process abundances for comparison to data from bulk meteorites
Maria Lugaro, Mattias Ek, Mária Pető +4
Analysis of bulk meteorite compositions has revealed small isotopic variations due to the presence of material (e.g., stardust) that preserved the signature of nuclear reactions oc…
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…
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…
The RADIOSTAR Project
Maria Lugaro, Benoit Côté, Marco Pignatari +12
Radioactive nuclei are the key to understanding the circumstances of the birth of our Sun because meteoritic analysis has proven that many of them were present at that time. Their…
Potassium Isotope Compositions of Carbonaceous and Ordinary Chondrites: Implications on the Origin of Volatile Depletion in the Early Solar System
Hannah Bloom, Katharina Lodders, Heng Chen +6
Solar system materials are variably depleted in moderately volatile elements (MVEs) relative to the proto-solar composition. To address the origin of this MVE depletion, we conduct…
Potassium Isotopic Compositions of Enstatite Meteorites
Chen Zhao, Katharina Lodders, Hannah Bloom +5
Enstatite chondrites and aubrites are meteorites that show the closest similarities to the Earth in many isotope systems that undergo mass-independent and mass-dependent isotope fr…
Do meteoritic silicon carbide grains originate from asymptotic giant branch stars of super-solar metallicity?
M. Lugaro, A. I. Karakas, M. Petö +1
We compare literature data for the isotopic ratios of Zr, Sr, and Ba from analysis of single meteoritic stardust silicon carbide (SiC) grains to new predictions for the slow neutro…
