A multi-frequency study of the SMC region around AX J0105-722
Abstract
We present a high-resolution multi-frequency study of the Small Magellanic Cloud (SMC) region around the X-ray pulsar AX J0105-722. From ROSAT PSPC images we resolve this source into several X-ray sources. We combine X-ray, radio-continuum and optical data to identify the sources: for RX J0105.1-7211 we propose an emission line star from the catalogue of Meyssonier & Azzopardi (1993) in the X-ray error circle as the likely optical counterpart. This catalogue contains several known Be/X-ray binaries strongly suggesting RX J0105.1-7211 as new Be/X-ray binary in the SMC. RX J0105.1-7211 is most probably also the counterpart of the ASCA X-ray pulsar AX. RX J0105.4-7209 confirms DEM S128 as supernova remnant (SNR) and RX J0105.5-7213 is very likely a background AGN.
