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…
A Reassessment of the Quasi-Simultaneous Arrival Effect in Secondary Ion Mass Spectrometry
Ryan Ogliore, Kazuhide Nagashima, Gary Huss +1
Quasi-simultaneous arrival (QSA) effects in secondary ion mass spectrometry can create mass-indepedent inaccuracies in isotope measurements when using electron multiplier detectors…
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…
