Abstract
ABSTRACT Broad-band 20-33 micron photometry is presented for a sample of cool stars. The long-wavelength flux is interpreted in terms of dust-shell models. It is found that the amount of silicate dust necessary to produce the observed 10 micron features can also produce the long-wavelength flux. The dust observations are used to derive lower limits for mass-loss rates. Sufficient 35 micron flux exists to pump the 1612 MHz OH masers for all stars observed in this sample, with the exception of R Aql. The data do not rule out the possibility of infrared pumping of the main-line masers.
