Scientific paper

With 14 years, V723Cas is the oldest nova in the Galaxy. We search for reasons for the long life time of this nova compared to all other novae. With an uninterrupted 60-ks XMM observation, covering one orbit, we can: (1) constrain the location of gas in the binary system using orbit phase-resolved EPIC spectra (2) study X-ray/UV variability, yielding the WD spin period, g mode oscillations, or evidence of renewed accretion disk activity (3) see correlations between X-ray and UV variability (4) investigate illumination effects of the companion with OM (5) determine from RGS whether the X-ray spectrum is a typical SSS spectrum, or whether it consists of overlapping emission lines. (6) search for emission lines yielding information on renewed accretion and cooling ejecta
