Production of radioactive Na in core-collapse supernovae: the Ne-E(L) component in presolar grains and its possible consequences on supernova observations
M. Pignatari, S. Amari, P. Hoppe +8
Presolar graphite grains carry the isotopic signatures of their parent stars. A significant fraction of presolar graphites shows isotopic abundance anomalies relative to solar for…
Isotopic ratios for C, N, Si, Al, and Ti in C-rich presolar grains from massive stars
Jordan Schofield, Marco Pignatari, Richard J Stancliffe +1
Certain types of silicon carbide (SiC) grains, e.g., SiC-X grains, and low density (LD) graphites are C-rich presolar grains that are thought to have condensed in the ejecta of cor…
Correlations of r-Process Elements in Very Metal-Poor Stars as Clues to their Nucleosynthesis Sites
Khalil Farouqi, Friedrich-Karl Thielemann, Stephan Rosswog +1
Various nucleosynthesis studies have pointed out that the r-process elements in very metal-poor (VMP) halo stars might have different origins. By means of familiar concepts from st…
Radioactive nuclei from cosmochronology to habitability
M. Lugaro, U. Ott, Á. Kereszturi
In addition to long-lived radioactive nuclei like U and Th isotopes, which have been used to measure the age of the Galaxy, also radioactive nuclei with half-lives between 0.1 and…
On the Origin of the Early Solar System Radioactivities. Problems with the AGB and Massive Star Scenarios
D. Vescovi, M. Busso, S. Palmerini +7
Recent improvements in stellar models for intermediate-mass and massive stars are recalled, together with their expectations for the synthesis of radioactive nuclei of lifetime $τ\…
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…
