The Extinction Coefficients in Mid Infrared and Far Infrared of Silicate and Iron-Oxide Minerals of Interest for Astronomical Observations
Abstract
Extinction measurements were made for some silicate and iron-oxide mineral grains in mid- and far-infrared region. For far-infrared region, high temperature magnesium silicates such as olivine and pyroxenes show the absorption spectra of steep dependence as λ-3 (λ being the wavelength) with some peak structure, but the spectrum of magnetite shows λ-1 dependence.
