SDSS J124058.03-015919.2: A new AM CVn star with a 37-minute orbital period
G. H. A. Roelofs, P. J. Groot, T. R. Marsh +3
We present high time resolution VLT spectroscopy of SDSS J124058.03-015919.2, a new helium-transferring binary star identified in the Sloan Digital Sky Survey. We measure an orbita…
Spectroscopy and near-infrared photometry of the helium nova V445 Puppis
Patrick A. Woudt, Danny Steeghs
Nova Puppis 2000 (V445 Pup) has been proposed as the first example of a helium nova. Recent optical spectroscopy of V445 Pup at V=19.91 mag obtained with IMACS on the 6.5-m Magella…
Bowen Fluorescence from Companion Stars in X-ray Binaries
J. Casares, D. Steeghs, R. I. Hynes +3
This paper will review a new technique of detecting companion stars in LMXBs and X-ray transients in outburst using the Bowen fluorescence lines at 4634-4640 Angs. These lines are…
SDSS J1240-01: A New AM CVn Candidate from the Sloan Digital Sky Survey
G. Roelofs, P. Groot, D. Steeghs +1
We report on the discovery of a new AM CVn candidate from the Sloan Digital Sky Survey, Data Release 1. Our first spectroscopic follow-up in the optical is presented and discussed…
Spiral waves in accretion discs
H. M. J. Boffin, D. Steeghs
In the first part of this article, we review the observational evidence for spirals in the accretion discs of cataclysmic variables. It is shown that with the increasing amount of…
A first look at cataclysmic variable stars from the 2dF QSO survey
T. R. Marsh, L. Morales-Rueda, D. Steeghs +9
The 2dF QSO survey is a spectroscopic survey of 48,000 point-sources selected by colour with magnitudes in the range 18.35 < B < 20.95. Amongst QSOs, white dwarfs, narrow-line gala…
