Protosolar Irradiation in the Early Solar System: Clues from Lithium and Boron Isotopes
Ming-Chang Liu, Larry R. Nittler, Conel M. O'D. Alexander +1
We report Li and B isotopic compositions of 10 Spinel-HIBonite spherules (SHIBs) separated from the Murchison meteorite, in order to understand their irradiation history in the ear…
Extreme 54Cr-rich nano-oxides in the CI chondrite Orgueil -Implication for a late supernova injection into the Solar System
Liping Qin, Larry R. Nittler, Conel M. O'D. Alexander +3
Systematic variations in 54Cr/52Cr ratios between meteorite classes (Qin et al., 2010a; Trinquier et al., 2007) point to large scale spatial and/or temporal isotopic heterogeneity…
Aluminum-, Calcium- And Titanium-Rich Oxide Stardust In Ordinary Chondrite Meteorites
Larry R. Nittler, Conel M. O'D. Alexander, Roberto Gallino +4
We report isotopic data for a total of 96 presolar oxide grains found in residues of several unequilibrated ordinary chondrite meteorites. Identified grain types include Al2O3, MgA…
On the asymptotic giant branch star origin of peculiar spinel grain OC2
M. Lugaro, A. I. Karakas, L. R. Nittler +4
Microscopic presolar grains extracted from primitive meteorites have extremely anomalous isotopic compositions revealing the stellar origin of these grains. The composition of pres…
