  title={Ju l 2 00 3 Gas in Dusty Debris Disks},
  author={R{\'e}ne Liseau},
The presence of gas in dusty debris disks around main-sequence stars is reviewed. We present new observational results for the most prominent representative of the class, viz. the southern naked-eye star β Pictoris. The spatial and spectral distribution of observed atomic lines from the disk around the star is reproducable by a Keplerian rotation model to a… CONTINUE READING
