Laboratory Analysis of Presolar Silicate Stardust

Silicates are the most abundant dust species observed around the atmospheres of oxygen-rich red giant stars. These condensates have recently been identified in interplanetary dust particles (IDPs) primitive meteorites and Antarctic micrometeorites. Their discovery allows for laboratory analysis on the nanometer scale of a representative component of stellar outflows.
