Tabulated data values
Tables of optical constants
In Ossenkopf et al. (1992) we have derived the optical constants of astronomical silicates in the shells of
oxygen-rich late-type stars and the diffuse interstellar medium.
silicate is typical for warm shells of late-type
stars. The oxygen-rich
silicate represents silicates in cooler shells and the diffuse
In Preibisch et al. (1993) we gave the
optical constants of amorphous carbon with a structure typical for cold molecular
clouds. Using an effective medium approach we computed the
optical constants of dirty ice containing 10% of amorphous carbon.
All data tables consist of three columns. The first one contains
the wavelength in cm. The second and third one contain the optical
constants n and k.
Tables of dust opacities
In Ossenkopf & Henning (1994) we have tabulated the dust opacities
for separated and coagulated dust particles in dense protostellar
All data tables consist of two columns. The first one contains
the wavelength in micron. The second one is the absorption cross section in cm^2 per gram of refractive material in the dust.
- MRN distribution of grains:
- MRN distribution of grains with thin ice mantles (0.5 times the volume of the refractory components):
- MRN distribution of grains with thick ice mantles (4.5 times the volume of the refractory components):
The tables here represent all dust opacities plotted in Fig. 5 of
the paper. They are an expansion of Table 1 in the sense that
additional opacity files are given for the intermediate gas
densities n(H)=10^5 cm^-3 and 10^7 cm^-3.
For the details of the derivation of all data I refer to the
mentioned publications (see the List of Publications).
