Presolar Silicon Carbide Grains of Types Y and Z: Their Strontium and Barium Isotopic Compositions and Stellar Origins
Nan Liu, Thomas Stephan, Sergio Cristallo +5
We report the Sr and Ba isotopic compositions of 18 presolar SiC grains of types Y (11) and Z (7), rare types commonly argued to have formed in lower-than-solar metallicity asympto…
New Multielement Isotopic Compositions of Presolar SiC Grains: Implications for Their Stellar Origins
Nan Liu, Jens Barosch, Larry R. Nittler +5
We report NanoSIMS Si and Mg-Al isotopic data (and C, N, and Ti isotopic data when available) for 85 submicron- to micron-sized presolar SiC grains from the CM2 Murchison meteorite…
Cluster analysis of presolar silicon carbide grains: evaluation of their classification and astrophysical implications
Asmaa Boujibar, Samantha Howell, Shuang Zhang +9
Cluster analysis of presolar silicon carbide grains based on literature data for 12C/13C, 14N/15N, δ30Si/28Si, and δ29Si/28Si including or not inferred initial 26Al/27Al data, reve…
On the mass and metallicity distribution of parent AGB stars of presolar SiC
Sergio Cristallo, Ambra Nanni, Gabriele Cescutti +5
The vast majority (>=90%) of presolar SiC grains identified in primitive meteorites are relics of ancient asymptotic giant branch (AGB) stars, whose ejecta were incorporated into t…
Magnetic-buoyancy Induced Mixing in AGB Stars: Presolar SiC Grains
Diego Vescovi, Sergio Cristallo, Maurizio Busso +1
Isotope ratios can be measured in presolar SiC grains from ancient Asymptotic Giant Branch (AGB) stars at permil-level (0.1\%) precision. Such precise grain data permit derivation…
Presolar Silicon Carbide Grains of Types Y and Z: Their Molybdenum Isotopic Compositions and Stellar Origins
Nan Liu, Thomas Stephan, Sergio Cristallo +8
We report Mo isotopic compositions of 37 presolar SiC grains of types Y (19) and Z (18), rare types commonly argued to have formed in lower-than-solar metallicity asymptotic giant…
