Some data which may be of use:
Recent Publications on Interstellar Dust
- "Astrodust" dielectric functions and scattering and absorption cross sections for spheroids
(see Draine & Hensley 2021a, ApJ 910:47).
Dielectric functions are provided for wavelengths from 1 A to 5 cm (12.4 keV to 2.6e-5 eV)
for selected axial ratios. Cross sections are provided for selected axial ratios and selected iizes (volume-equivalent radii from 3.16 A to 5.01um)
- PAH Emission spectra: PAH emission for heating by a wide range of radiation fields (from a 3 Myr-old starburst to the old stallar population of the M31 bulge. Spectra are provided for inndividula PAH sizes, and for selected size distributions.
See Draine, Li, Hensley, Hunt, Sandstrom, & Smith 2021, ApJ 917:3.
- Infrared Emission from the silicate-graphite-PAH model for interstellar dust (Draine & Li 2007)
- Synthetic infrared emission spectra (1cm > lambda > 1 micron)
silicate-graphite-PAH dust models, for various dust mixtures,
and for a wide range of starlight intensities.
The starlight is assumed to have the spectrum estimated by
Mathis, Mezger & Panagia (1983).
- Dust models include size distributions that reproduce
- the average Milky Way extinction curve with R_V=3.1
- LMC 2 extinction curve
- SMC Bar extinction curve
- Spectra convolved with IRAS, COBE-DIRBE,
Spitzer (IRAC, MIPS, IRS Peak-Up),
Akari (IRC, FIS),, and Herschel (PACS, SPIRE)
Synthetic Extinction Curves
- Extinction, Absorption, and Albedo as a function of wavelength for
a mixture of carbonaceous (PAH and graphitic)
and silicate grains with R_V = 3.1 extinction law
