Optical studies of the X-ray transient XTE J2123-058 - II. Phase resolved spectroscopy
R. I. Hynes, P. A. Charles, C. A. Haswell +2
We present time-resolved spectroscopy of the soft X-ray transient XTE J2123-058 in outburst. Spectral coverage of 3700-6700A was achieved spanning two orbits of the binary. The str…
