Polarization within the Interstellar 4430 Å Absorption Band

Nature Physical Science volume 229, pages 234–236 (1971)Cite this article

Abstract

IT was reported by Nandy and Seddon1 recently that the wavelength dependence of interstellar polarization for the star HD 198478 shows a conspicuous band-like feature in a wavelength region coincident with the 4430 Å interstellar absorption band. The increase in polarization near the band centre above that of the neighbouring continuum could be in the range 50–100% within the accuracy of the existing data. No satisfactory theoretical interpretation of this phenomenon has yet been given. It seems likely that the new data may hold a clue which could help in the understanding of the nature of diffuse interstellar bands.
