Description G29-38 is the prototype and brightest example of a white dwarf orbited by rocky debris from a tidally-destroyed planetary body. Because this warm debris orbits within 1 solar radius, the parent body must have originated in a more distant region. Thus, we suspect a persistent planetesimal belt at G29-38, that contains a substantial number and mass of remnant planetary bodies, as this best accounts for the larger family of disk- and metal -polluted white dwarfs. We propose Herschel PACS observations to detect cold dust from within this remnant population of minor planets. A lack of cool dust favors a scenario in which the observed warm dust resulted from the tidal destruction of a major rocky planet. The proposed observations are the best chance to detect such a cold disk around any metal-enriched white dwarf, and will provide insight into the fate of planetary systems at A- and F-type stars.

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 ┬Ám range, bridging the gap between earlier infrared space missions and groundbased facilities.
