ABSTRACT
Stardust found in chondrites and interplanetary dust
particles (IDPs) has given us important information on stars
that existed before the formation of our solar system.
Recent studies have expanded the range of presolar grain
types to silicates, the most dominant constituent of
planetary materials. Previous searches of micrometeorites,
extraterrestrial dust grains collected from polar ice and
snow, yielded no presolar grains. Here, we report newly
discovered presolar silicates from Antarctic micrometeorites
(AMMs). A part of this study has been presented
previously.
