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…
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…
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…
Common Occurrence of Explosive Hydrogen Burning in Type II Supernovae
Nan Liu, Thomas Stephan, Patrick Boehnke +6
We report Mo isotopic data for 16 15N-rich presolar SiC grains of type AB (14N/15N<solar, AB1) and their correlated Sr and Ba isotope ratios when available. Eight of the 16 AB1 gra…
J-type carbon stars: A dominant source of 14N-rich presolar SiC grains of type AB
Nan Liu, Thomas Stephan, Patrick Boehnke +6
We report Mo isotopic data of 27 new presolar SiC grains, including 12 14N-rich AB (14N/15N>440, AB2) and 15 mainstream (MS) grains, and their correlated Sr and Ba isotope ratios w…
The Future of Stardust Science
A. J. Westphal, J. C. Bridges, D. E. Brownlee +13
Recent observations indicate that >99% of the small bodies in the Solar System reside in its outer reaches --- in the Kuiper Belt and Oort Cloud. Kuiper Belt bodies are probably th…
COSIMA-Rosetta calibration for in-situ characterization of 67P/Churyumov-Gerasimenko cometary inorganic compounds
Harald Krüger, Thomas Stephan, Cécile Engrand +15
COSIMA (COmetary Secondary Ion Mass Analyser) is a time-of-flight secondary ion mass spectrometer (TOF-SIMS) on board the Rosetta space mission. COSIMA has been designed to measure…
