J/PASP/105/1127    Distribution of Dust in  Solar Neighborhood   (Gaustad+ 1993)

The Distribution of Interstellar Dust in the Solar Neighborhood Gaustad J.E., Van Buren D. <Publ. Astron. Soc. Pac. 105, 1127 (1993)> =1993PASP..105.1127G (SIMBAD/NED RefCode)
ADC_Keywords: Infrared sources - 350; Colors - 235; Interstellar medium - 360 Abstract: The authors have surveyed the IRAS data base at the positions of the 1808 O6--B9.5 stars in The Bright Star Catalog for extended objects with excess emission ("hotspots") at 60 microns, indicating the presence of interstellar dust at the location of the star. The spatial distribution of the dust clouds and the filling factor for dust in the interstellar medium are discussed in Gaustad and van Buren (1993). The data included here give the measured infrared fluxes and radii, and the inferred absorption optical depths, densities, and color temperatures for the 302 objects detected. Also included are a list of the BSC objects for which no data could be obtained, and a list of those hotspots which also show detectable reflection nebulosity. File Summary:
