Abstract (from CDS):

We present five band imaging of the Vega debris disc obtained using the Herschel Space Observatory. These data span a wavelength range of 70-500µm with full-width half-maximum angular resolutions of 5.6-36.9''. The disc is well resolved in all bands, with the ring structure visible at 70 and 160µm. Radial profiles of the disc surface brightness are produced, and a disc radius of 11'' (∼85AU) is determined. The disc is seen to have a smooth structure thoughout the entire wavelength range, suggesting that the disc is in a steady state, rather than being an ephemeral structure caused by the recent collision of two large planetesimals.
