FUV Scattering by Dust in Orion
arXiv:astro-ph/0601388 · doi:10.1111/j.1365-2966.2006.10071.x
Abstract
We have modelled diffuse far-ultraviolet spectrum observed by FUSE near M42 as scattering of starlight from the Trapezium stars by dust in front of the nebula. The dust grains are known to be anomalous in Orion with Rv = 5.5 and these are the first measurements of the FUV optical properties of the grains outside of ``normal'' Milky Way dust. We find an albedo varying from 0.3 0.1 at 912 Åto 0.5 0.2 at 1020 Åwhich is consistent with theoretical predictions.
