Scientific paper

We present JHK photometry and spectroscopy of RX J0019.8+2156. The spectrum appears to be dominated by the accretion disc to at least 2.4 microns, over any other source of emission. We find Paschen, Brackett and HeII lines strongly in emission, but no HeI. There are satellite lines approximately 850km/s either side of the strongest, unblended hydrogen lines. These satellite lines may be the spectral signature of jets from the accretion disc.
