| Description | We propose SPIRE photometry of the brightest 8 brown dwarfs detected at both 70 and 160um in our GT1 program that has just completed observing 50 BDs. These 8 BDs are expected to be detected at 250-350um and half are also likely detectable at 500um. The addition of longer wavelength data for even this 20% of our sample will enable much stronger limits to be placed on the geometry of the outer disks, the grain size distribution, and the total disk masses. With the ultimate goal of adding ALMA photometry and imaging at longer wavelengths, we will be able to derive much more accurate physical parameters of the disks around these objects by using the entire SED from 1um to 1mm. |

| Mission Description | Herschel was launched on 14 May 2009! It is the fourth cornerstone mission in the ESA science programme. With a 3.5 m Cassegrain telescope it is the largest space telescope ever launched. It is performing photometry and spectroscopy in approximately the 55-671 µm range, bridging the gap between earlier infrared space missions and groundbased facilities. |
