Scientific paper

IRAS observations of the Pleiades region are reported. The data show large flux densities at 12 μm and 25 μm, extended over the optical nebulosity. This strong excess emission, implying temperatures of a few hundred degrees Kelvin, indicates a population of very small grains in the Pleiades. It is suggested that these grains are similar to the small grains needed to explain the surface brightness measurements made in the ultraviolet.
