| Description | We propose to observe GD 362 to measure the amount of cold dust orbiting this white dwarf which is already known to possess warm dust. There are two models to account for the large amount of atmospheric hydrogen in this externally-polluted star whose atmosphere is largely helium. (1) The star is accreting from a single Mars-mass parent body. In this case there is no reason to expect cold dust. (2) The star is accreting from an ensemble of 100s of Ceres-mass asteroids; a large amount of cold dust likely is present. If so, the source could be detected with PACS. |

| 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. |
