Anomalous X-ray Pulsars (AXPs) are an exotic population of pulsating X-ray sources, which increasing evidence suggests are highly magnetized neutron stars ("magnetars"). With only six known AXPs,however, we are limited in our understanding of the global properties of this population, and of their relation to other types of neutron star. Recently, 8.0-second pulsations were identified from CXOU J010043.1-721134, an X-ray source in the Small Magellanic Cloud. We present a new series of Chandra observations, aimed at ascertaining whether or not this object is the seventh known AXP. We present a detailed temporal and spectral analysis of these observations, and discuss corresponding implications for the nature of this source.
