SDSS J080449.49+161624.8: A peculiar AM CVn star from a colour-selected sample of candidates
G. H. A. Roelofs, P. J. Groot, D. Steeghs +6
We describe a spectroscopic survey designed to uncover an estimated ~40 AM CVn stars hiding in the photometric database of the Sloan Digital Sky Survey (SDSS). We have constructed…
ULTRACAM observations of two accreting white dwarf pulsators
C. M. Copperwheat, T. R. Marsh, V. S. Dhillon +6
In this paper we present high time-resolution observations of GW Librae and SDSS J161033.64-010223.3 -- two cataclysmic variables which have shown periodic variations attributed to…
The hidden HI-massive LIRG HIZOA J0836-43: Inside-out galaxy formation
M. E. Cluver, T. H. Jarrett, P. N. Appleton +6
HIZOA J0836-43 is an extreme gas-rich (=7.5$\times10^{10} M_{\sun}$) disk galaxy which lies hidden behind the strongly obscuring Vela region of the Milky Way. Utilizin…
Newly Discovered Cataclysmic Variables from the INT/WFC Photometric H alpha Survey of the Northern Galactic Plane
A. R. Witham, C. Knigge, A. Aungwerojwit +7
We report the discovery of 11 new cataclysmic variable (CV) candidates by the Isaac Newton Telescope (INT) Photometric H alpha Survey of the northern Galactic plane (IPHAS). Three…
Outbursts of EX Hydrae Revisited
N. Mhlahlo, D. A. H. Buckley, V. Dhillon +3
We present optical spectroscopy of EX Hya during its 1991 outburst. This outburst is characterised by strong irradiation of the front face of the secondary star by the white dwarf,…
The Discovery of a Persistent Quasi-Periodic Oscillation in the Intermediate Polar TX Col
N. Mhlahlo, D. A. H. Buckley, V. S. Dhillon +8
We report on the detection of an ~5900 s quasi-periodic variation in the extensive photometry of TX Col spanning 12 years. We discuss five different models to explain this period.…
