Abstract (from CDS):

We present an ISO 25 µm photometric survey of a sample of 81 nearby main-sequence stars in order to determine the incidence of ``warm'' dust disks. All stars were detected by ISO. We used an empirical relation to estimate the photospheric flux of the stars at 25µm. We find 5 stars (6%) with excess above the photospheric flux which we attribute to a Vega-like disk. These stars show disk temperatures not warmer than 120K. Our study indicates that warm disks are relatively rare. Not a single star in our sample older than 400Myr has a warm disk. We find an upper limit of Mdisk=2x10–5M for the mass of the disks which we did not detect.
