VLA search for 2-cm continuum radiation from Comet Halley

Journal Article · · Icarus; (United States)

The presently reported VLA search for icy-grain 2-cm continuum emission in the halo surrounding Comet Halley in mid-November, 1985, notes the 3-sigma upper limit for flux density at this wavelength to be consistent with the detections at 1.3 and 3.5 mm by Altenhoff et al. (1986) only in the case where the sources of the emission are inefficiently radiating particles. These particles are surmised to be either icy or small refractory grains; in either case, they would be sub-mm-sized and slightly dirty. 26 references.
