Six white dwarfs with circumstellar silicates.

JURA M., FARIHI J. and ZUCKERMAN B.

Abstract (from CDS):

Spitzer Space Telescope spectra reveal 10 µm silicate emission from circumstellar dust orbiting six externally polluted white dwarfs. Micron-size glasses with an olivine stoichiometry can account for the distinctively broad wings that extend to 12 µm; these particles likely are produced by tidal disruption of asteroids. The absence of infrared polycyclic aromatic hydrocarbon features is consistent with a scenario where extrasolar rocky planets are assembled from carbon-poor solids.
