Photometric Variability of Be/X-Ray Pulsar Binaries in the Small Magellanic Cloud

We have studied the photometric variability of 10 SMC Be/X-ray pulsars using MACHO and OGLE-II data. For some of these systems we have found periodic behavior, including orbital outbursts and/or nonradial pulsations of the Be star. For others we were unable to identify any clear photometric periodicity, although their long-term light curves show significant structure. We present periodograms, phase dispersion minimization variances, and folded light curves for the systems that exhibit periodic photometric variability.
