Correlated X-ray and Optical Variability in V404 Cyg in Quiescence
R. I. Hynes, P. A. Charles, M. R. Garcia +11
We report simultaneous X-ray and optical observations of V404 Cyg in quiescence. The X-ray flux varied dramatically by a factor of >20 during a 60ks observation. X-ray variations w…

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…
