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.
The oxygen-deficient
silicate is typical for warm shells of late-type
stars. The oxygen-rich
silicate represents silicates in cooler shells and the diffuse
interstellar medium.
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
cores.
- 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):
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.
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).
