Current Status of the SuperWASP Project
D. J. Christian, D. L. Pollacco, W. I. Clarkson +16
We present the current status of the SuperWASP project, a Wide Angle Search for Planets. SuperWASP consists of up to 8 individual cameras using ultra-wide field lenses backed by hi…
Stream-fed Accretion in Intermediate Polars
Coel Hellier
I review the observational evidence for stream-fed accretion in intermediate polars. Recent work on the discless system V2400 Oph confirms the pole-flipping model of stream-fed acc…
Does TV Col Have the longest Recorded Positive Superhumps?
A. Retter, C. Hellier, T. Augusteijn +1
Re-examination of extensive photometric data of TV Col reveals evidence for a permanent positive superhump. Its period (6.4 h) is 16 percent longer than the orbital period and obey…
Recent results on intermediate polars
Coel Hellier
I review recent activity in the field of intermediate polars, concentrating on: the mode of accretion (disc-fed, disc-overflow or discless); accretion curtains (the transition regi…
YY Draconis and V709 Cassiopeiae: two intermediate polars with weak magnetic fields
A. J. Norton, A. P. Beardmore, Alasdair Allan +1
We present data from long ROSAT HRI observations of the intermediate polars YY Dra and V709 Cas which show that V709 Cas, like YY Dra, exhibits a double-peaked X-ray pulse profile.…
Indirect imaging of the accretion stream in HU Aquarii
M K Harrop-Allin, Mark Cropper, P Hakala +2
We apply our technique for indirect imaging of the accretion stream to UBVR eclipse profiles of HU Aqr obtained when the system was in a high state. We perform model fits to the ec…
