Abstract (from CDS):

We report optical and infrared (IR) observations of the ASCA X-ray pulsar system AX J0051-733. The relationship between the X-ray source and possible optical counterparts is discussed. Long-term optical data from over 7yr are presented which reveal both a 1.4-d modulation and an unusually rapid change in this possible binary period. Various models are discussed.
