The contribution of Oxygen to the “30”, “26” and “20” μm features
The IR absorption spectra of several macromolecules of interest for amorphous carbonaceous cosmic dust were simulated by means of a commercially available stateof-the-art chemical code. None of the three unidentified far IR features show up significantly in the absence of oxygen in the structure. By contrast, peripheral OH (hydroxy) gives rise to strong modes in the “30” band. The “26” and “20”...
متن کاملGalaxy Counts at 450 Μm and 850 Μm
Surveys of the distant Universe have been made using the SCUBA submillimeter(submm)-wave camera at the JCMT. 450and 850μm data is taken simultaneously by SCUBA in the same 5-arcmin2 field. Deep 850-μm counts of high-redshift dusty galaxies have been published; however, at 450 μm both the atmospheric transmission and antenna efficiency are lower, and the atmospheric noise is higher, and so only ...
متن کاملAn 850 μm survey for dust around solar mass stars
We present the results of an 850 μm JCMT/SCUBA survey for dust around 13 nearby solar mass stars. The dust mass sensitivity ranged from 5 × 10 to 0.16 M⊕. Three sources were detected in the survey, one of which (HD 107146) has been previously reported. One of the other two submillimeter sources, HD 104860, was not detected by IRAS and is surrounded by a cold, massive dust disk with a dust tempe...
متن کاملCertification of NIST SRM 1961: 30 μm Diameter Polystyrene Spheres
This report describes the certification of SRM 1961, an NIST Standard Reference Material for particle diameter. It consists of an aqueous suspension of monosize 30 μm diameter polystyrene spheres. The primary technique used optical microscopy; it gave a mean diameter value [Formula: see text] and a standard deviation of the size distribution σD = 0.21 μm. Over 2000 spheres were measured. The su...
متن کاملThe screening of the 11.3-μm SiC feature by carbonaceous mantles in circumstellar shells
Silicon carbide, a refractory material, condenses near the photospheres of Crich AGB stars, giving rise to a conspicuous emission feature at 11.3 μm. In the presence of a stellar wind, the SiC grains are carried outwards to colder regions, where less refractory carbonaceous material can condense, either by itself or in mantles upon SiC grains. Enough carbon can condense on the latter that their...
