XMM-Newton observations of the eclipsing polar V2301 Oph
Gavin Ramsay, Mark Cropper
We present XMM-Newton observations of the eclipsing polar V2301 Oph which cover nearly 2.5 binary orbital cycles and 2 eclipses. This polar is believed to have the lowest magnetic…
X-ray emissions from two-temperature accretion flows within a dipole magnetic funnel
Curtis J. Saxton, Kinwah Wu, Joao. B. G. Canalle +2
We investigate the hydrodynamics of accretion channelled by a dipolar magnetic field (funnel flows). We consider situations in which the electrons and ions in the flow cannot maint…
Twisted accretion curtains in the intermediate polar FO Aquarii
P. A. Evans, Coel Hellier, Gavin Ramsay +1
We report on a ~37-ks XMM-Newton observation of the intermediate polar FO Aquarii, presenting X-ray and UV data from the EPIC and OM cameras. We find that the system has changed fr…
Accretion Flow Along a Dipolar Field: Application to Intermediate Polars
J. B. G. Canalle, Kinwah Wu, Mark Cropper +2
A hydrodynamic formulation for accretion flow channeled by a dipolar magnetic field is constructed using a curvi-linear coordinate system natural to the field structure. We solve t…
3D eclipse mapping in AM Herculis systems - `Genetically modified fireflies'
Pasi J. Hakala Mark Cropper Gavin Ramsay
In order to map the 3-dimensional location and shape of the emission originating within the accretion stream in AM Her systems, we have investigated the possibilities of relaxing t…
RX J0806+15: the shortest period binary?
G. Ramsay, P. Hakala, M. Cropper
The X-ray source RX J0806+15 was discovered using ROSAT, and shows an X-ray light curve with a prominent modulation on a period of 321.5 sec. We present optical observations in whi…
