From a Spitzer archival search and cross-correlation of the TYCHO-2 and IRAS catalogs we have found a sample of previously unknown warm IR excess stars. Warm IR excess emission at these stars is indicative of our Sun's zodiacal dust analog and is likely due to terrestrial planet building processes. Some of the most interesting dusty stars previously revealed by IRAS and Spitzer are characterized by warm excess emission. Now we propose to perform follow-up observations to help constrain the nature of the dust around our new sample of potentially exciting excess stars. In particular, our sample hints at the existence of a class of young stars so enshrouded in nearby (warm) orbiting material that X-ray fluxes are substantially reduced.
