The massive neutron star or low-mass black hole in 2S0921-630
T. Shahbaz, J. Casares, C. Watson +4
We report on optical spectroscopy of the eclipsing Halo LMXB 2S0921-630, that reveals the absorption line radial velocity curve of the K0III secondary star with a semi-amplitude K_…
Evidence for a Black Hole in the X-ray transient GS 1354-64 (=BW Cir)
J. Casares, C. Zurita, T. Shahbaz +2
We present the first radial velocity curve of the companion star to BW Cir which demonstrates the presence of a black hole in this X-ray transient which recorded outbursts in 1987…
Optical spectroscopy of flares from the black hole X-ray transient A0620-00 in quiescence
T. Shahbaz, R. I. Hynes, P. A. Charles +5
We present a time-resolved spectrophotometric study of the optical variability in the quiescent soft X-ray transient A0620-00. Superimposed on the double-humped continuum lightcurv…
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…
Long-term optical/infrared variability in the quiescent X-ray transient V404 Cyg
C. Zurita, J. Casares, R. I. Hynes +3
We present the results of optical and infrared photometry of the quiescent X-ray transient V404 Cyg during the period 1992-2003. The ellipsoidal modulations extracted from the most…
The Nonradially-Pulsating Primary of the Cataclysmic Variable GW Librae
L. van Zyl, B. Warner, D. O'Donoghue +11
The dwarf nova GW Librae is the first cataclysmic variable discovered to have a primary in a white dwarf instability strip, making it the first multi-mode, nonradially-pulsating st…
