Observations of the extreme-ultraviolet transient REJ1255+266: a short outburst of a WZ Sge system?

WHEATLEY P.J., BURLEIGH M.R. and WATSON M.G.

Abstract (from CDS):

We present a previously unpublished ROSAT Wide Field Camera observation of the transient source RE J1255+266 made just 4d before the discovery observations. The source is not detected, limiting the duration of the outburst to be less than expected for a superoutburst of a WZ Sge system.

We also present a marginal detection of X-ray emission from RE J1255+266 using ASCA. The most probable luminosity is 6x1029erg.s–1, which is very similar to WZ Sge itself.

We discuss the nature of the source in the light of these observations, and conclude that it is most probably a WZ Sge system, but that the observed outburst must have been a normal dwarf nova outburst.
