    Preliminary results of the Air Force infrared sky survey (1981)
    In:  Other Sources
    Details
    Publication Date: 2019-06-28
    Description: The paper presents a review of the Air Force Infrared Sky Survey with a discussion of the current status of the survey and an account of efforts to verify results contained in the AFCRL and AFGL catalogs. An overview of the AFGL catalog and subsets is given; 71% of the sources listed in the AFGL catalog are identified with sources in the Two Micron Sky Survey. Combining the data in the AFGL and TMSS catalogs yields information on the energy distributions of the brighter IR sources over four octaves. Attention is then given to studies of particular classes of objects found in the AFGL catalog, concentrating on objects not identified with stars in the TMSS or the Catalogue of Bright Stars. Finally, a summary is given of the relative populations of various classes of infrared sources found in the AFGL catalog, including a discussion of its extragalactic content.

    Infrared observations of the eclipse of Epsilon Aurigae Direct measurement of the 500 K secondary at 5, 10, and 20 microns (1984)
    In:  Other Sources
    Details
    Publication Date: 2019-06-28
    Description: Photometric data of the once-every-27 yr eclipse of the Epsilon Auriga F supergiant are reported. The data were taken on 28 nights from July 1982-May 1984 and covered the 1.25-20 microns region. The secondary object was identified at 5, 10, and 20 microns when the eclipse removed 48 percent of the F star's light. The data indicated that the secondary is a compact object surrounded by a large optically thick cloud, with a luminosity under 0.01 of the primary. The secondary's mass is, however, more than 14 solar masses.
