Chemically homogeneous compact spheres: calculations with new optical constants

for the following dust mixtures (corresponding to different dust temperatures):
olivine
olivine+iron
olivine+iron+pyroxene
olivine+iron+pyroxene+troilite
olivine+iron+pyroxene+troilite+refractory organics
olivine+iron+pyroxene+troilite+refractory organics+volatile organics
olivine+iron+pyroxene+troilite+refractory organics+volatile organics+water ice

The corresponding Rosseland mean opacities are valid for a gas density ng ~ 10-8 g/cm3.

The wavelength dependent opacity tables consist of five columns. The first one contains the wavelength in micron. The second one is the (published) radiative pressure cross section, i.e. the extinction cross section corrected for anisotropic scattering. The third, fourth and fifth columns are the extinction, absorption and scattering cross sections, respectively.
The Rosseland mean opacity tables consist of two columns. The first one contains the temperature in Kelvin. The second one is the Rosseland mean opacity.
The opacities are given in cm2 per gram of refractive material.
Some of the data presented here are published in Henning & Stognienko.
