Abstract: | This paper is a continued examination of luminescence of cosmic dust, in particular the dust in reflecting nebulae. A model of frozen hydrocarbon particles in the form of a nucleus with a polycrystalline mantle is proposed. The basic properties of these particles, as well as the technique for obtaining spectra of the nebula CED 201 on the 2 meter TLS telescope with a Naismith focus spectrograph, are described. Part of the detected unknown emission in the spectrum of CED 201 is identified as photoluminescence of frozen hydrocarbon particles that form part of the dust component of the nebular matter.__________Translated from Astrofizika, Vol. 48, No. 3, pp. 445–453 (August 2005). |
