Evidence for Lattice Bands in Interstellar Grains

Nature volume 216, pages 249–250 (1967)Cite this article

Abstract

THERE is considerable evidence from the infrared photometry of Johnson1–3 that the wavelength range 3–10µ is associated with strong emission and absorption of radiation by interstellar grains. Several early type stars which exhibit excess infrared emission have been shown3 to possess extended circumstellar envelopes. It has been proposed by Stein4 that the thermal radiation from a size distribution of grains heated to about 300° K could explain this excess radiation. In such a model, which contains several arbitrary parameters, the precise location of the maximum emission at about 10µ must be regarded as rather fortuitous.
