J/A+A/293/833        Circumstellar silicate grains                (David+, 1995)

The complex dielectric function for circumstellar silicate grains based on the IRAS data David P., Pegourie B. <Astron. Astrophys. 293, 833 (1995)> =1995A&A...293..833D (SIMBAD/NED Reference)
ADC_Keywords: Spectra, infrared; Extinction Keywords: (stars:) circumstellar matter - infrared: stars - dust, extinction - molecular data Description: Based on the radiative transfer modelling studies relative to a large sample of circumstellar envelopes (∼300 sources) undertaken by David & Papoular (1990A&A...237..425D) the complex dielectric function for circumstellar silicate grains is derived in the wavelength region from 0.35 to ∼1355m.
