摘要：XTE J1748􀀀288 is a black hole X-ray transient which went into outburst in 1998 June. The X-ray lightcurves showed fairly canonical morphologies with minor variations on the “Fast Rise Exponential Decay” profile. The radio source, however, reached an unusually high flux density of over 600 mJy. This high radio flux was accompanied by high (> 20%) fractional linear polarisation, the variability of which was anti-correlated with the flux density. We use this variability to discuss possible depolarisation mechanisms, to predict the underlying behaviour of the core/jet components and to study polarisation properties within the context of internal shock models for jets.
