XMM-Newton Observations of Recent Galactic Novae
Abstract
We report on the observations of five recent galactic classical novae, performed with XMM-Newton. Some of them show emission in the whole range from 0.2 to 8.0 keV, up to 3 years after the explosion. Nova Oph 1998 shows clear evidence of resumed accretion less than 3 years after its explosion, indicating a very fast recovery of the cataclysmic variable after the nova outburst. In another case, Nova Sgr 1998, it is difficult to disentangle if the emission is produced in the ejecta and/or in the accretion stream.
