Abstract

It is shown that the protoplanetary dust condensations around the T-Tauri star RU Lup, proposed by Gahmet al. (1974), would be unstable to tidal disruption if they are bound only by gravitational forces. There are extreme conditions under which the condensations would be stable, but such conditions would easily be verifiable observationally.
