European astronomers have found that an Xray pulsar designated AX J1910.7+0917 has the slowest spin period among other objects in this class. the new findings in a paper published May 4 on arXiv.org. X-ray pulsars (also known as accretion-powered pulsars) are sources displaying strict periodic variations in Xray intensity, consisting of a magnetized neutron star in orbit with a normal stellar companion. In these binary systems, the Xray emission is powered by the release of gravitational potential energy as material is accreted from a massive companion. Xray pulsars are among the most luminous objects in the X-ray sky.
