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.

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).
