Abstract
ABSTRACT Five late-type stars with circumstellar envelopes were observed with the James Clark Maxwell Telescope (JCMT) on 1988 Feb. 7-8. The stars IK Tau, Alpha Ori, VY CMa, CW Leo and RW LMi 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.
