Light curve oscillations and flux decline in the Be/X-ray binary Swift J1626.6-5156
Abstract
We report on the long-term light curve periodicity and recent decline in flux of the Be/X-ray binary Swift J1626.6-5156 (Palmer et al., ATel #678). The compact object is a X-ray pulsar, with spin period ~15.37s (Markwardt & Swank, ATel #679). The source has been monitored by RXTE since late December 2005, and the light curve can be viewed through the link given below. On ~JD 2453910, or late June 2006, the source began to show quasi-periodic behavior in its X-ray flux.
