Scientific paper

The 10 micron spatial visibility data for 17 late-type stars presented, have multiple observations for most of the stars. A majority of their surrounding circumstellar dust shells are at least partially resolved with a 2.3 m telescope. Single and two-component Gaussians are fitted to these visibility data, and results are compared with the models of Rowan-Robinson and Harris (1982).
