The few Vega-type stars whose dusty debris disks have been resolved show this dust lies in cool Kuiper belt-like rings. However, roughly half of all debris disk candidates exhibit little or no cool dust, since their dust emission peaks at around 25 microns. By analogy with the solar system, these warm disks would lie mid-way between the asteroid and Kuiper belt regions in their systems. As such these disks could represent the Kuiper belt-like rings of truncated planetary systems, or the destruction of massive interplanetary asteroid/comet belts. We have conducted a mid-IR observing programme of stars identified as warm debris disk candidates in the IRAS catalogue using the TIMMI2 instrument on the 3.6m telescope at La Silla. In this poster we present our results, which confirm the excess for 7 of our candidates, and determine probable radial locations for the dust.
