Presolar silicate grains: Abundances, isotopic and elemental compositions, and the effects of secondary processing

C Floss, P Haenecour - Geochemical Journal, 2016 - jstage.jst.go.jp
Close to a thousand presolar silicate grains have been identified since their initial discovery
in interplanetary dust particles (IDPs) just over ten years ago. Studies have shown that …
