Abstract

Broad-band photometric observations of IRC + 10216 in five wavelength intervals from 50 to 1000 μ are reported. The observed radiation is interpreted as thermal emission from dust in the extended molecular cloud heated by the compact 2-20 μ source as the core of the cloud. The shape of the 50-1000 μ spectrum suggests that the emissivity of the dust particles varies approximately as λ^(-1) over this spectral interval. The mass of dust inferred from the far-infrared emission is comparable with the mass of heavy molecules in the cloud.

Westbrook, who died in 1975 June after these observations were made. We thank Drs. E. E. Becklin, G. Knapp, T. Kuiper, and M. Morris for useful discussions; Dr. W. Forrest for assisting with the 350 μ, observations and for making the 18 μ, observation; and the staff and crew of NASA Kuiper AIRO for their excellent cooperation during the airborne work.
