The β Pictoris Disk: Peculiar or Just Young?

Jack J. Lissauer, Dana E. Backman
2002 International Astronomical Union Colloquium  
AbstractThe starβPictoris is not in itself very remarkable; however, it is surrounded by a dust disk that is much more prominent than any other main sequence star's disk. The proximity ofβPic and the nearly edge-on viewing geometry of the disk enhance its appearance, but do not fully account for the disk's prominence. While it is possible thatβPic's disk is intrinsically unusual, a more likely explanation is thatβPic is simply a very young (~ 20 Myr old) main sequence star with a consequently
