Scientific paper

We propose to continue the monitoring of the M31 core with five 23ks XMM-Newton EPIC and five 20ks Chandra HRC-I observations equally distributed from Nov 2009 to mid Feb 2010 to determine additional light curves for short supersoft source (SSS) states of optical novae. SSS states with <100 d duration indicate accreting massive white dwarfs. They are proposed as SN Ia progenitors and determining their frequency is very important. We will correlate detected sources with novae from optical monitoring. With a nova rate in the field of ~25/yr and SSS states lasting from weeks to years we will follow light curves of many novae. Durations of the nova SSS state will allow us to constrain envelope and white dwarf masses. We will also monitor time variability of ~200 M31 centre X-ray sources (mostly XRBs).
