Intermediate-mass asymptotic giant branch stars and sources of Al, Fe, Pd, and Hf in the solar system
G. J. Wasserburg, Amanda I. Karakas, Maria Lugaro
We explore the possibility that the short-lived radionuclides Al, Fe, Pd, and Hf inferred to be present in the proto-solar cloud originated from $3-8…
The intermediate neutron-capture process and carbon-enhanced metal-poor stars
Melanie Hampel, Richard J. Stancliffe, Maria Lugaro +1
Carbon-enhanced metal-poor (CEMP) stars in the Galactic Halo display enrichments in heavy elements associated with either the s (slow) or the r (rapid) neutron-capture process (e.g…
Stellar yields from metal-rich asymptotic giant branch models
Amanda I. Karakas, Maria Lugaro
We present new theoretical stellar yields and surface abundances for three grids of metal-rich asymptotic giant branch (AGB) models. Post-processing nucleosynthesis results are pre…
Origin of the p-process radionuclides 92Nb and 146Sm in the early Solar System and inferences on the birth of the Sun
Maria Lugaro, Marco Pignatari, Ulrich Ott +4
The abundances of 92Nb and 146Sm in the early Solar System are determined from meteoritic analysis and their stellar production is attributed to the p process. We investigate if th…
