The dust properties of a short period comet: comet P/Borrelly.

LI A. and GREENBERG J.M.

Abstract (from CDS):

We have calculated the thermal emission spectrum of the dust of comet P/Borrelly (1994l), a short-period comet (Jupiter family), from 3µm to 14µm as well as the 10µm silicate feature in terms of the comet dust model as porous aggregates of interstellar grains. Compared to comet P/Halley dust, the dust grains of P/Borrelly appear to be relatively more processed (more carbonized), less fluffy, and richer in smaller particles. The fluffy aggregate model of silicate core-amorphous carbon mantle grains with a porosity P=0.85 can match the observational data. To generalize the dust properties of short-period comets, systematic observations of the thermal emission spectra and the silicate features for a large set of samples are needed.

within arcsec The VizieR photometry tool allows for easy visualization of photometry points extracted around the Simbad position from photometry-enabled catalogues in VizieR.
The search radius has to be specified by the user. It is currently limited to a maximum of 30 arcsec. It depends mostly on the precision or quality of the coordinates (SIMBAD and VizieR catalogs), the resolution of the images from which the sources were extracted, source extent, and source crowding.
Suggestions are: crowded field: 0.5 to 1.5 arcsec, 3 arcsec otherwise; uncertain coordinates (SIMBAD quality E or coordinates without reference): 5 to 30 arsec (risky!). sed-help-icon
