IRAS high-resolution (12, 25, 60, and 100 microns) observations of the Rho Ophiuchi cloud core are presented. Analysis of the 12 micron data reveals 18 individual embedded sources with a surface brightness of greater than 1 Jy/sq arcmin and far-infrared luminosities ranging between 0.2-21 solar luminosities. Infrared observations collected at the Infrared Telescope Facility in Mauna Kea, Hawaii in July 1984 and April 1985 are utilized to identify 13 near-infrared objects in the IRAS data. The ground-based fluxes are compared to IRAS density fluxes; it is observed that the ground-based fluxes are lower by about a factor of three than the IRAS fluxes, indicating the presence of midinfrared emission due to hot dust on angular scales greater than 6-13 arcsec. It is noted that the IRAS observations provide a more complete description of the embedded population in the Rho Ophiuchi core than previous studies.
