X-Rays: Binaries
Scientific paper
We present recent observations of the X-ray pulsar SAX J1324-6200 obtained in December 2007 with the Swift satellite, significantly improving the source localization over previous data and providing a new measurement of the spin period P=172.84 s. A single object that is consistent in colors with a highly reddened early type star is visible in the X-ray error box. The period is significantly longer than what was obtained in 1997, indicating that SAX J1324-6200 has been spinning down at an average rate of ˜6 × 10-9 s s-1. We discuss the possible nature of the source, showing that it most likely belongs to the class of low-luminosity, persistent Be/neutron star binaries.
