We present observations of Nova Cas 1993 (V705 Cas) obtained with ISO.
We have detected the [OIV] fine structure line at
26m and [CII] at 157
m. Preliminary analysis suggest that
elemental abundances similar to those in the ejecta of DQ Her, and a hot
(~ 700000K) stellar remnant, are consistent with the ISO
observations. The dust shell, which was prominent in the near infrared in
ground-based observations, was not detected by ISO, unless the stellar
remnant had `switched off' by the time of the ISO observations. On the
other hand, we may have detected a pre-existing dust shell.
