Echoes from the companion star in Sco X-1
T. Muñoz-Darias, I. G. Martinez-Pais, J. Casares +5
We present simultaneous X-ray (RXTE) and optical (ULTRACAM) narrow band (Bowen blend/HeII and nearby continuum) observations of Sco X-1 at 2-10 Hz time resolution. We find that the…
XMM-Newton observations of AM CVn binaries: V396 Hya & SDSS J1240-01
Gavin Ramsay, Paul J. Groot, Tom Marsh +3
We present the results of XMM-Newton observations of two AM CVn systems - V396 Hya and SDSS J1240-01. Both systems are detected in X-rays and in the UV: neither shows coherent vari…
XMM-Newton observations of AM CVn binaries
Gavin Ramsay, Pasi Hakala, Tom Marsh +3
We present the results of XMM-Newton observations of four AM CVn systems -- AM CVn, CR Boo, HP Lib and GP Com. Their light curves show very different characteristics. The X-ray lig…
The systemic velocities of four long-period cataclysmic variable stars
R. C. North, T. R. Marsh, U. Kolb +2
Although a large number of orbital periods of cataclysmic variable stars (CVs) have been measured, comparison of period and luminosity distributions with evolutionary theory is aff…
Gravitational lensing in eclipsing binary stars
T. R. Marsh
I consider the effect of the gravitational deflection of light upon the light curves of eclipsing binary stars, focussing mainly upon systems containing at least one white dwarf co…
Radial velocity measurements of white dwarfs
P. F. L. Maxted, T. R. Marsh, C. K. J. Moran
We present 594 radial velocity measurements for 71 white dwarfs obtained during our search for binary white dwarfs and not reported elsewhere. We identify three excellent candidate…
