XMM-Newton observations of the polars EV UMa, RX J1002-19 and RX J1007-20

Gavin Ramsay, Mark Cropper

We present XMM-Newton data of three strongly magnetic cataclysmic variables (polars) EV UMa, RX J1002-19 and RX J1007-20. These include the polar with the shortest orbital period (…

XMM-Newton EPIC observations of Her X-1

Gavin Ramsay, Silvia Zane, Mario Jimenez-Garate +2

We present spin-resolved X-ray data of the neutron star binary Her X-1 taken using the EPIC detectors on XMM-Newton. The data were taken at three distinct epochs through the 35 day…

X-ray spectroscopy of Eta Carinae with XMM-Newton

Maurice A. Leutenegger, Steven M. Kahn, Gavin Ramsay

We present XMM-Newton observations of the luminous star Eta Carinae, including a high resolution soft X-ray spectrum of the surrounding nebula obtained with the Reflection Grating…

STJ Observations of the Eclipsing Polar HU Aqr

C. M. Bridge, Mark Cropper, Gavin Ramsay +6

We apply an eclipse mapping technique to observations of the eclipsing magnetic cataclysmic variable HU Aqr. The observations were made with the S-Cam2 Superconducting Tunnel Junct…

X-ray Spectroscopy of the IP PQ Gem

Cynthia H. James, Gavin Ramsay, Mark Cropper +1

Using RXTE and ASCA data, we investigate the roles played by occultation and absorption in the X-ray spin pulse profile of the Intermediate Polar PQ Gem. From the X-ray light curve…

High-Resolution X-ray Spectroscopy of Hercules X-1 with the XMM-Newton RGS: CNO Element Abundance Measurements and Density Diagnostics of a Photoionized Plasma

M. A. Jimenez-Garate, C. J. Hailey, J. W. den Herder +2

We analyze the high-resolution X-ray spectrum of Hercules X-1, an intermediate-mass X-ray binary, which was observed with the XMM-Newton Reflection Grating Spectrometer. We measure…

First X-ray observations of the polar CE Gru

Gavin Ramsay, Mark Cropper

We report the detection of the polar CE Gru in X-rays for the first time. We find evidence for a dip seen in the hard X-ray light curve which we attribute to the accretion stream o…

XMM-Newton observations of the asynchronous polar BY Cam

Gavin Ramsay, Mark Cropper

We report observations of the asynchronous polar BY Cam made using XMM-Newton. We find evidence for two accretion regions which have significantly different spectra. In both region…

XMM-Newton EPIC observations of Her X-1

G. Ramsay, S. Zane, M. A. Jimenez-Garate +2

We present spin-resolved X-ray data of the neutron star binary Her X-1. We find evidence that the Iron line at 6.4 keV originates from the same location as the blackbody X-ray comp…
