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…
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…
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…
