We searched for submillimeter emission around 10 Vega-type stars and one Herbig Ae star with the four-color bolometer at 1300 µm and the 19 channel bolometer array at 870 µm using the Heinrich Hertz Telescope at the Submillimeter Telescope Observatory. All of our sources were undetected at 870 µm. In the case of HD 131156, we have a 3 σ detection at 1300 µm. We report a flux of 6.25±1.88 mJy for the HD 131156 disk and a corresponding dust mass of 2.4±0.7 lunar masses. However, we did not detect HD 131156 at 870 µm, so we are cautious about the 1300 µm detection. We performed follow-up infrared observations of HD 131156 using MIRLIN at the Palomar 200 inch telescope, which resolved both components of the binary. The data are photospheric, implying that the system does not have a hot, inner dust component. We report submillimeter upper limits on fluxes for the remaining systems.
