What Can Infrared Spectra Tell Us about the Crystallinity of Nanosized Interstellar Silicate Dust Grains?

ACS Earth and Space Chemistry, 2019
Infrared (IR) spectroscopy is the main technique used to identify and characterize silicate dust grains in astronomical environments. From IR spectra, the fraction of crystalline dust particles can be estimated and used to help understand the processing ...

The Plausibility of Silicate-Core Ice-Mantle Grains

Astrophysics and Space Science, 1975
Extinction curves for silicate-core ice-mantle grains are computed and compared with the infrared spectral data on the BN object in the Orion nebula. A ratio of outer mantle to core radius of 1.3 which best fits this data suggests that silicate-core ice-mantle grains are unlikely to contribute a major part to the total visual extinction coefficient of ...
