Supersoft X-ray source states of optical novae in the disk of M 31
Abstract
We propose Target of Opportunity (ToO) observations to characterise the supersoft X-ray emission of optical novae in the disk of M 31 with four 20 ks XMM-Newton EPIC observations during July 2010 to mid-August 2010 and January 2011 to mid-February 2011. These observations will allow to perform spectral analysis of M 31 disk novae during their supersoft X-ray source state (SSS) and to determine effective temperatures and luminosities. The probability of triggering all four observations on four different novae is high. Our observations will double the number of M 31 disk novae with known SSS spectra. This will help to study the differences between bulge novae and disk novae in the X-ray regime.
