Abstract:
Previous studies have found that Vega is surrounded by an extended
debris disc that is very smooth in the far infrared, but displays
possible clumpiness at 850um and dust emission peaks at 1.3mm.
We reobserved Vega at 1.3mm with PdBI to constrain its circumstellar
dust distribution.
Description:
Our observations of a three-field mosaic have a factor of two higher
sensitivity than previous observations.
