Abstract

Infrared spectral properties of silicate grains in interplanetary dust particles (IDPs) were compared with those of astronomical silicates. The ∼10-micrometer silicon-oxygen stretch bands of IDPs containing enstatite (MgSiO 3 ), forsterite (Mg 2 SiO 4 ), and glass with embedded metal and sulfides (GEMS) exhibit fine structure and bandwidths similar to those of solar system comets and some pre–main sequence Herbig Ae/Be stars. Some GEMS exhibit a broad, featureless silicon-oxygen stretch band similar to those observed in interstellar molecular clouds and young stellar objects. These GEMS provide a spectral match to astronomical “amorphous” silicates, one of the fundamental building blocks from which the solar system is presumed to have formed.
