Millimeter imaging of the β Pictoris debris disk: evidence for a planetesimal belt.

WILNER D.J., ANDREWS S.M. and HUGHES A.M.

Abstract (from CDS):

We present observations at 1.3 mm wavelength of the β Pictoris debris disk with beam size 4".3x2".6 (83x50 AU) from the Submillimeter Array. The emission shows two peaks separated by ∼7'' along the disk plane, which we interpret as a highly inclined dust ring or belt. A simple model constrains the belt center to 94±8 AU, close to the prominent break in slope of the optical scattered light. We identify this region as the location of the main reservoir of dust-producing planetesimals in the disk.
