ULTRACAM Photometry of the ultracompact binaries V407 Vul and HM Cnc
S. C. C. Barros, T. R. Marsh, V. S. Dhillon +6
V407 Vul (RXJ1914.4+2456) and HM Cnc (RXJ0806.3+1527) are X-ray emitting stars with X-ray light curves that are 100% modulated on periods of 569 and 321 seconds respectively. These…
White dwarfs in the European Galactic Plane Surveys (EGAPS)
L. Morales-Rueda, P. J. Groot, R. Napiwotzki +2
The space density of white dwarfs is highly uncertain even nearby. This results from the fact that the known sample of white dwarfs is largely incomplete in part because most white…
SDSS J0926+3624, the first eclipsing AM CVn star, as seen by ULTRACAM
T. R. Marsh, V. S. Dhillon, S. Littlefair +6
We present light curves of SDSS J0926+3624, the first eclipsing AM CVn star, observed with the high-speed CCD camera ULTRACAM on the WHT. We find unusually that the accreting white…
Recent observational progress in AM CVn binaries
G. Ramsay, C. Brocksopp, P. Groot +9
We present the results of some recent research on AM CVn systems. We present: X-ray/UV observations made using XMM-Newton; the X-ray grating spectrum of RX J1914+24; preliminary re…
Short timescale variability in the Faint Sky Variability Survey
L. Morales-Rueda, P. J. Groot, T. Augusteijn +3
We present the V band variability analysis of the point sources in the Faint Sky Variability Survey on time scales from 24 minutes to tens of days. We find that about one percent o…
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…
