Presolar stardust in asteroid Ryugu
Jens Barosch, Larry R. Nittler, Jianhua Wang +121
We have conducted a NanoSIMS-based search for presolar material in samples recently returned from C-type asteroid Ryugu as part of JAXA's Hayabusa2 mission. We report the detection…
Coordinated Analysis of Two Graphite Grains from the CO3.0 LAP 031117 Meteorite: First Identification of a CO Nova Graphite and a Presolar Iron Sulfide Subgrain
Pierre Haenecour, Christine Floss, Jordi Jose +5
Presolar grains constitute remnants of stars that existed before the formation of the solar system. In addition to providing direct information on the materials from which the sola…
Tungsten isotopic compositions in stardust SiC grains from the Murchison meteorite: Constraints on the s-process in the Hf-Ta-W-Re-Os region
J. N. Ávila, M. Lugaro, T. R. Ireland +7
We report the first tungsten isotopic measurements in stardust silicon carbide (SiC) grains recovered from the Murchison carbonaceous chondrite. The isotopes 182W, 183W, 184W, 186W…
Presolar Diamond in Meteorites
Sachiko Amari
Presolar diamond, the carrier of the isotopically anomalous Xe component Xe-HL, was the first mineral type of presolar dust that was isolated from meteorites. The excesses in the l…
He and Ne ages of large presolar silicon carbide grains: Solving the recoil problem
U. Ott, P. R. Heck, F. Gyngard +4
Knowledge about the age of presolar grains provides important insights into Galactic chemical evolution and the dynamics of grain formation and destruction processes in the Galaxy.…
Heavy Element Abundances in Presolar Silicon Carbide Grains from Low-Metallicity AGB Stars
P. Hoppe, J. Leitner, C. Vollmer +4
Primitive meteorites contain small amounts of presolar minerals that formed in the winds of evolved stars or in the ejecta of stellar explosions. Silicon carbide is the best studie…
