Scientific paper

We propose to observe a classical or recurrent nova in outburst with the Chandra LETG grating, if it is observed to turn into a luminous supersoft X-ray source using Swift. We also define alternative criteria to trigger the observation in case an observation with XMM-Newton is possible. Our aims are: a) Analyse the spectra of the hot white dwarf (WD) atmosphere, deriving effective temperature, abundances and effective gravity, b) Assess how common it is to find a significant leftover mass on the WD after a nova outburst, c) Measure the short term variability due to non radial oscillations of the white dwarf, d) Possibly also study the supersoft X-ray emission originating in the ejected nebula.
