Continuum Emission from the Star-forming Regions Cepheus A and B
Abstract
Observations of the continuum emission of the Cep A and Cep B dust clouds at 1300 and 865 microns are presented. These data, together with flux densities determined from the IRAS and with additional observations made at shorter wavelengths, define the continuum spectra of the dust emission integrated over the sources. From these spectra luminosities, dust temperatures, column densities, masses, filling factors, clump sizes, and volume densities are derived. The results are compared with the observations of molecular clouds in the near vicinity of Cep A and with the characteristics of other galactic dust clouds.
