Determining the mass of the accreting white dwarf in magnetic CVs using data
Gavin Ramsay
We have extracted spectra of 20 magnetic Cataclysmic Variables (mCVs) from the RXTE archive and fitted them using the X-ray continuum method of Cropper et al to determine the mass…
Detection of the optical counterpart of the proposed double degenerate polar RX J1914+24
Gavin Ramsay, Mark Cropper, Kinwah Wu +2
We have detected the optical counterpart of the proposed double degenerate polar RX J1914+24. The I band light curve is modulated on the 9.5 min period seen in X-rays. There is no…
Effects of Gravity on the Structure of Postshock Accretion Flows in Magnetic Cataclysmic Variables
Mark Cropper, Kinwah Wu, Gavin Ramsay +1
We have calculated the temperature and density structure of the hot postshock plasma in magnetically confined accretion flows, including the gravitational potential. This avoids th…
Simultaneous optical polarimetry and X-ray observations of the magnetic CV CP Tuc (AX J2315--592)
Gavin Ramsay, Stephen Potter, David Buckley +1
CP Tuc (AX J2315--592) shows a dip in X-rays which lasts for approximately half the binary orbit and is deeper in soft X-rays compared with hard X-rays. It has been proposed that t…
