Astromineralogy: Dust in another solar system
Steve Desch1
Abstract
A star surrounded by a disk of dust could be a solar system in the making. Analysis of radiation from the dust suggests that there might be belts of comets or asteroids, and even a planet, orbiting the star.
Astromineralogy is an exciting new field, a combination of astronomy and mineralogy. The goal is to use astronomical obser- observations — usually at mid-infrared (MIR) wavelengths (2–30 
m) — to determine the size, crystal structure and chemical make-up of dust grains in space, often around protostars.
