A SEARCH FOR 100 MU-M AND SUB-MM EMISSION IN DWARF NOVAE

Harrison & Gerhz [AJ, 103, 243 (1992)] noted that IRAS had apparently detected a few quiescent dwarf novae at 100 mu m. This possible detect ion was intriguing as dwarf novae were not anticipated to be emitters of such long-wavelength radiation. In order to confirm or place limits on this emission, we have undertaken a reanalysis of the IRAS databas e for four of their ''100 mu m'' dwarf novae. We have also made prelim inary sub-mm radio observations of three additional dwarf novae. We fi nd null detections for all our sources in both the IRAS database and i n the sub-mm radio range.
