Description We propose to continue the monitoring of the M31 core with 5x23ks XMM EPIC and 5x20ks Chandra HRC-I observations equally distributed from Nov 2010 to mid Feb 2011 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 (WDs). They are proposed as SN Ia progenitors and deter- mining their frequency is very important. We will correlate detected sources with novae from optical monitoring. With a nova rate in the field of ~38-yr and SSS states lasting from weeks to years we will follow light curves of many novae. Durations of the SSS state will allow us to constrain envelop and WD masses. We will also monitor time variability of ~200 M31 X-ray sources (XRBs)

Mission Description The European Space Agency's (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESA's second cornerstone of the Horizon 2000 Science Programme. It carries 3 high throughput X-ray telescopes with an unprecedented effective area, and an optical monitor, the first flown on a X-ray observatory. The large collecting area and ability to make long uninterrupted exposures provide highly sensitive observations.
Since Earth's atmosphere blocks out all X-rays, only a telescope in space can detect and study celestial X-ray sources. The XMM-Newton mission is helping scientists to solve a number of cosmic mysteries, ranging from the enigmatic black holes to the origins of the Universe itself. Observing time on XMM-Newton is being made available to the scientific community, applying for observational periods on a competitive basis.
