A radio survey of supersoft, persistent and transient X-ray sources in the Magellanic Clouds
R. P. Fender, K. Southwell, A. K. Tzioumis
We present a radio survey of X-ray sources in the Large and Small Magellanic clouds with the Australia Telescope Compact Array at 6.3 and 3.5 cm. Specifically, we have observed the…
T Pyxidis: The First Cataclysmic Variable with a Collimated Jet
T. Shahbaz, M. Livio, K. A. Southwell +1
We present the first observational evidence for a collimated jet in a cataclysmic variable system; the recurrent nova T Pyxidis. Optical spectra show bipolar components of H wit…
The X-ray off-state of the supersoft source CAL 83 and its interpretation
C. Alcock et al
We consider simultaneous optical data obtained during the recent X-ray turn-off of CAL83. Combining the optical behaviour with the observed X-ray decay time, we show that a model o…
The optical counterpart of the supersoft Small Magellanic Cloud transient pulsar RX~J0059.2-7138
K. A. Southwell, P. A. Charles
We identify the probable optical counterpart of the SMC supersoft source, RX~J0059.2-7138, with a ~14th magnitude star lying within the X-ray error circle. We present high re…
The nature of the supersoft X-ray source RX~J0513--69
K. A. Southwell, M. Livio, P. A. Charles +2
We present spectroscopy and photometry of the LMC supersoft binary system RX~J0513.9-6951. We derive a refined spectroscopic period of P~d, which is consistent with…
