XMM-Newton observations of OY Car III: OM light curve modelling, X-ray timing and spectral studies

Pasi Hakala, Gavin Ramsay

We revisit the XMM-Newton observations of the dwarf nova OY Car taken in July 2000 which occured shortly after an outburst. Ramsay et al (2001a) found a prominent energy dependent…

XMM-Newton observations of three short period polars: V347 Pav, GG Leo and EU UMa

Gavin Ramsay, Mark Cropper, K. O. Mason +2

We present phase-resolved XMM_Newton data of three short period polars: V347 Pav, GG Leo and EU UMa. All three systems show one dominant accretion region which is seen for approxim…

The obscured QSO 1SAX J1218.9+2958

Nicola Loaring, M. J. Page, G. Ramsay

We present results from XMM-Newton observations of the obscured QSO 1SAX J1218.9+2958. We find that the previously reported optical and soft X-ray counterpart positions are incorre…

Spin up in RX J0806+15 - the shortest period binary

Pasi Hakala, Gavin Ramsay, Kinwah Wu +4

RX J0806+15 has recently been identified as the binary system with the shortest known orbital period. We present a series of observations of RX J0806+15 including new optical obser…

A search for X-ray variability in the open cluster NGC 2516

Gavin Ramsay, Louise Harra, Hilary Kay

We present the results of a search for X-ray variability in the galactic open cluster NGC 2516. This cluster has been observed on 8 occasions using XMM-Newton making it an excellen…

The XMM-Newton-MSSL survey of Polars

Gavin Ramsay, Mark Cropper

The XMM-Newton-MSSL survey of polars is a snapshot survey of nearly 40 polars. We present the initial results, with an emphasis on the energy balance in these systems and the numbe…

Variability of the Accretion Stream in the Eclipsing Polar EP Dra

C. M. Bridge, Mark Cropper, Gavin Ramsay +3

We present the first high time resolution light curves for six eclipses of the magnetic cataclysmic variable EP Dra, taken using the superconducting tunnel junction imager S-Cam2.…
