Forming the dusty ring in HR 4796A.

Abstract (from CDS):

We describe planetesimal accretion calculations for the dusty ring observed in the nearby A0 star HR 4796A. Models with initial masses of 10-20 times the minimum-mass solar nebula produce a ring with a width of 7-15 AU and a height of 0.3-0.6 AU at 70 AU in ∼10 Myr. The ring has a radial optical depth of ∼1. These results agree with limits derived from infrared images and from the excess infrared luminosity.
