Scientific paper

We propose a 50-ks XMM-Newton observation of the unusual neutron star X-ray binary SAX J2224.9+5421. Our target was discovered by BeppoSAX/WFC when it exhibited a thermonuclear X-ray burst. Follow-up observations aiming to constrain the persistent emission were performed ~8 h later and detected the source at a 0.5-10 keV luminosity of ~1E33 erg/s. This is very peculiar since neutron star binaries are generally considered to be in quiescence at luminosities of ~1E31-1E33 erg/s, while they display accretion outbursts with luminosities of ~1E34-1E38 erg/s. With the proposed observation we aim for a detailed investigation of the X-ray spectrum of SAX J2224.9+5421 to find clues explaining its unusual behavior.
