HST Observations of X-Ray Transients
C. A. Haswell, R. I. Hynes
Results from an HST/multiwavelength campaign on the 1996 outburst of GRO J1655-40 are reported. We find evidence for an approximately isothermal outer disk in GRO J1655-40 during t…
Hubble Space Telescope Observations of the Black Hole X-ray Transient GRO J0422+32 Near Quiescence
R. I. Hynes, C. A. Haswell
We present HST/FOS ultraviolet and optical spectroscopy of the black hole X-ray transient GRO J0422+32 shortly before the system reached quiescence. We find that the accretion spec…
Echoes from an Irradiated Disc in GRO J1655-40
R. I. Hynes, K. O'Brien, Keith Horne +2
We demonstrate correlated rapid variability between the optical/UV and X-ray emission for the first time in a soft X-ray transient, GRO J1655-40: HST light curves show similar feat…
The 1996 Outburst of GRO J1655-40: The Challenge of Interpreting the Multi-wavelength Spectra
R. I. Hynes, C. A. Haswell, C. R. Shrader +6
We report on the results of a campaign to observe the SXT GRO J1655-40 in outburst using HST, XTE and GRO and AAT. This outburst was qualitatively quite different to other SXT outb…
