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…
Oxygen Isotopic Composition of an Enstatite Ribbon of Probable Cometary Origin
Ryan C. Ogliore, Donald E. Brownlee, Kazuhide Nagashima +5
Filamentary enstatite crystals are found in interplanetary dust particles of likely cometary origin but are very rare or absent in meteorites. Crystallographic characteristics of f…
Oxygen Isotopic Composition of Coarse- and Fine-grained Material from Comet 81P/Wild 2
Ryan C. Ogliore, Kazuhide Nagashima, Gary R. Huss +3
Individual particles from comet 81P/Wild 2 collected by NASA's Stardust mission vary in size from small sub-m fragments found in the walls of the aerogel tracks, to large fragme…
Relics of ancient post-AGB stars in a primitive meteorite
Manavi Jadhav, Marco Pignatari, Falk Herwig +3
Graphite is one of the many presolar circumstellar condensate species found in primitive meteorites. While the isotopic compositions of low-density graphite grains indicate an orig…
Heterogeneous distribution of Al-26 at the birth of the Solar System
Kentaro Makide, Kazuhide Nagashima, Alexander N. Krot +5
It is believed that Al-26, a short-lived (t1/2 = 0.73 Ma) and now extinct radionuclide, was uniformly distributed in the nascent Solar System with the initial Al-26/Al-27 ratio of…
