Large far-infrared excesses in some nearby main-sequence stars, revealed by the Infrared Astronomical Satellite (IRAS), have been interpreted as being due to thermal radiation from dust orbiting the stars, heated to about 100K by the stellar radiation (Aumann et al. 1984; Aumann 1985; Sadakane and Nishida 1986). The existence of solid circumstellar material is commonly interpreted in the context of planet formation, and the dust has been suggested to be formed by collisions of planetesimals (Nakano 1987, 1988).
