Clues to Stellar Evolution from Microscopy of Star Dust

Abstract

Micron-sized dust grains that formed in stars older than the Sun can be found in the matrices of some meteorites. Analysis of the structure and composition of this star dust in the transmission electron microscope (TEM) provides important constraints to stellar condensation models and spectroscopic stellar observations. Additional benefits of these presolar grain studies include the development of techniques for the micromanipulation of critical dust samples and a better understanding of the materials stability in extreme environments.
