An anti-correlation between X-ray luminosity and H-alpha equivalent width in X-ray binaries
R. P. Fender, D. M. Russell, C. Knigge +3
We report an anticorrelation between continuum luminosity and the equivalent width (EW) of the H-alpha emission line in X-ray binary systems. The effect is evident both in a univer…
An Overview of the Bowen Survey; detecting donor star signatures in Low Mass X-ray Binaries
Remon Cornelisse, Jorge Casares, Teo Munoz-Darias +4
In this paper we give a review of the Bowen fluorescence survey, showing that narrow emission lines (mainly NIII and CIII lines between 4630 and 4660 A) appear to be universally pr…
Multiwavelength Observations of EXO 0748--676 -- II. Emission Line Behavior
K. J. Pearson, R. I. Hynes, D. Steeghs +6
We present optical and ultraviolet spectra, lightcurves, and Doppler tomograms of the low-mass X-ray binary EXO 0748-676. Using an extensive set of 15 emission line tomograms, we s…
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…
Echoes in X-ray Binaries
K. O'Brien, K. Horne, R. Hynes +3
We present a method of analysing the correlated X-ray and optical/UV variability in X-ray binaries, using the observed time delays between the X-ray driving lightcurves and their r…
Detection of superhumps in XTE J1118+480 approaching quiescence
C. Zurita, J. Casares, T. Shahbaz +8
We present the results of our monitoring of the halo black-hole soft X-ray transient (SXT) XTE J1118+480 during its decline to quiescence. The system has decayed 0.5 mags from Dece…
