Abstract

We have modelled diffuse far-ultraviolet (FUV) spectrum observed by the Far Ultraviolet Spectroscopic Explorer (FUSE) near M42 as the scattering of the starlight from the Trapezium stars by dust in front of the nebula. The dust grains are known to be anomalous in Orion with R_V = 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 Å to 0.5 ± 0.2 at 1020 Å which is consistent with theoretical predictions.
