Geometrical constraints upon the unipolar model of V407 Vul and RXJ0806.3+1527
S. C. C. Barros, T. R. Marsh, P. Groot +5
V407 Vul and RX J0806.3+1527 are X-ray emitting stars with X-ray light curves that are 100% modulated on periods of 569 and 321 seconds respectively. These periods and no others ar…
XMM-Newton observations of the ultra-compact binary RX J1914+24
Gavin Ramsay, Pasi Hakala, Kinwah Wu +4
We present XMM-Newton observations of the 569 sec period system RX J1914+24 (V407 Vul). This period is believed to represent the binary orbital period making it an ultra-compact bi…
XMM-Newton observations of UW CrB -- detection of X-ray bursts and evidence for accretion disc evolution
P. Hakala, G. Ramsay, P. Muhli +4
UW CrB (MS1603+2600) is a peculiar short period X-ray binary that exhibits extraordinary optical behaviour. The optical light curve shape of the system changes drastically from nig…
Properties of serendipitous X-ray flares discovered in XMM-Newton observations
Duncan Trenholme, Gavin Ramsay, Carl Foley
We present the results of a search of the XMM-Newton public data archive for stellar X-ray flares. We find eight flaring sources for which we identify 7 optical counterparts. Three…
XMM-Newton observations of the eclipsing polar EP Dra
Gavin Ramsay, C. M. Bridge, Mark Cropper +3
We present XMM-Newton observations of the eclipsing polar EP Dra which cover nearly 3 binary orbital cycles. The X-ray and UV data show evidence for a prominent dip before the ecli…
First observation of Jupiter by XMM-Newton
G. Branduardi-Raymont, R. F. Elsner, G. R. Gladstone +4
We present the first X-ray observation of Jupiter by XMM-Newton. Images taken with the EPIC cameras show prominent emission, essentially all confined to the 0.2-2.0 keV band, from…
