Scientific paper

Five late-type stars with circumstellar envelopes were observed with the James Clerk Maxwell Telescope (JCMT) on 1988 February 7-8. The stars IK Tauri, Alpha Orionis, VY Canis Majoris, CW Leonis, and RW Leonis Minoris were observed in the 450, 800, and 1100 micron wavebands. These data were combined with existing measurements at shorter wavelengths for each star. The combined data were fitted to a circumstellar-dust-shell model based on the computer code by Leung (1975). Derived parameters, including mass-loss rates, are presented for the observed stars.
