Transmission Electron Microscopy of an AOA-Like Presolar Grain from Semarkona
Abstract
We detail TEM microstructural and chemical observations of an unusual AOA-like presolar grain from Semarkona with implications for circumstellar conditions around its progenitor AGB star as well as secondary processes on its asteroidal parent body.
