Rapid optical spectroscopy of X-ray binaries with Keck II
Kieran O'Brien
The large collecting area of 4+ metre class telescopes allows atronomers to observe bright objects on faster timescales than previously possible. In order to exploit this capabilit…
ULTRACAM - an ultra-fast, triple-beam CCD camera
Vik Dhillon, Tom Marsh, the ULTRACAM team
ULTRACAM is an ultra-fast, triple-beam CCD camera which has been designed to study one of the few remaining unexplored regions of observational parameter space - high temporal reso…
Echoes in X-ray binaries; mapping the accretion flow
K O'Brien, K Horne
In X-ray binaries much of the optical/UV emission arises from X-rays reprocessed by material in the accretion disk, stream and the companion star. The resulting reprocessed variabi…
Polars -- multisite emission -- multiwavelength observation
Axel D. Schwope, K. Beuermann, D. A. H. Buckley +12
We review the main observational characteristics of AM Herculis stars (polars) at X-ray, EUV, UV, IR and optical wavelengths. Particular emphasis is given to multi-epoch, multi-wav…
