Abstract

We focus on two systems. The first is the Be/X-ray binary Swift J1626.6-5156, discovered in outburst by the Swift Burst Alert Telescope (BAT) in December 2005. Monitoring by the Rossi X-ray Timing Explorer (RXTE) has revealed a 45-day quasi-period in its long-term light curve, one cycle of which was observed in near-simultaneity by the Swift UV/optical Telescope (UVOT) and X-Ray Telescope (XRT). We present the long-term spectral evolution, including that of a cyclotron line with fundamental energy 10 keV, as well as the long-term timing analysis.

The second source is RXTE J1710-281, a low-mass X-ray binary that exhibits X-ray bursts and eclipses. Some interesting features are seen in the light curve, including one double burst and one burst triplet. We have calculated intensities and spectral colors and have performed a timing analysis to search for the neutron star's spin period and quasi-periodic oscillations. An early result is the detection of a low-frequency QPO at 3 Hz in the burst emission.
