The Case Against Graphite Particles in Interstellar Space
Authors:NC Wickramasinghe  AN Wickramasinghe  F Hoyle
Institution:(1) Department of Applied Mathematics and Astronomy, University College, Cardiff, U.K.
Abstract:Graphite flakes are excluded as a major component of interstellar grains because their ultraviolet extinction peaks occur at wavelengths longward of 2700 Å. Mie calculations for spherical graphite particles are shown to have no physical or astronomical relevance.
