Presolar silicate grains: Abundances, isotopic and elemental compositions, and the effects of secondary processing
presolar grains silicates nucleosynthesis isotopes AGB stars
2017/4/10
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 silicates are ...
