Meteoritic grains and the interstellar reddening curve
Abstract
The interstellar extinction curve contains information on the nature of interstellar grains. The model of silicate grains is known to provide good fits to the IR and visible part of the curve, however, the conspicuous UV hump on the extinction curve is generally attributed to extinction by small graphite grains. A laboratory investigation of the extinction by small grains obtained by shock-induced disintegration of the stony meteorite Saratov in water is described which shows that silicate grains (rather than graphite grains) are responsible for the UV hump.
