Abstract: We observed eight Vega-like stars at 850 μm with SCUBA on the JCMT at Mauna Kea, Hawaii; all are predicted to have high dust content. We marginally detected 49 Ceti (4 σ), previously detected in CO (Zuckerman et al. 1995). We derive a dust mass of ∼ 8 Mmoon, resulting in a gas-to-dust ratio of ∼ 20. We also detected HD 627, but the emission is extended and centered east of the star, suggesting interstellar rather than circumstellar origin.
