Explosive Nucleosynthesis in Core-Collapse Type II Supernovae: Insights from new C, N, Si, and Al-Mg isotopic compositions of presolar grains
Nan Liu, Conel M. O'D. Alexander, Bradley S. Meyer +3
We report C, N, Si, and Al-Mg isotope data for 39 presolar X silicon carbide (SiC) and four silicon nitride grains - a group of presolar grains that condensed in the remnants of co…
Chromium on Mercury: New results from the MESSENGER X-Ray Spectrometer and implications for the innermost planet's geochemical evolution
Larry R. Nittler, Asmaa Boujibar, Ellen Crapster-Pregont +6
Mercury, the innermost planet, formed under highly reduced conditions, based mainly on surface Fe, S, and Si abundances determined from MESSENGER mission data. The minor element Cr…
Tracing the history of an unusual compound presolar grain from progenitor star to asteroid parent body host
Sheryl A. Singerling, Larry R. Nittler, Jens Barosch +3
We conducted a TEM study of an unusual oxide-silicate composite presolar grain (F2-8) from the unequilibrated ordinary chondrite Semarkona. The presolar composite grain is relative…
