An IRAS search for dust in globular clusters
The IRAS Point-Source Catalog, Small-Scale Structure Catalog, and HCON1Sky Brightness Images were searched for sources of emission that werespatially coincident with any of 144 globular clusters. The purpose wasto measure or place upper limits on the amount of thermal dust emissionfrom the clusters, which would lead to estimates and upper limits to themass of intraglobular dust. Sputtering by hot gas in the galactic halocan destroy dust grains and thus possibly explain the absence of dust inglogular clusters.
