The Effects of a Stellar Encounter on a Planetesimal Disk

Abstract

We investigate the effects of a passing stellar encounter on a planetesimal disk through analytical calculations and numerical simulations, and derive the boundary radius (aplaneta_{\rm planet}) outside which planet formation is inhibited by disruptive collisions with high relative velocities.Comment: 25 pages, 11 figures, included in 15 tex-files, 7 ps-files and 4 eps-file
