Evidence for Lattice Bands in Interstellar Grains


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… (More)
