Further insight on the hypervelocity white dwarf, LP 40-365 (GD 492): a nearby emissary from a single-degenerate Type Ia supernova
R. Raddi, M. A. Hollands, D. Koester +4
The recently discovered hypervelocity white dwarf LP 40-65 (aka GD 492) has been suggested as the outcome of the failed disruption of a white dwarf in a sub-luminous Type Ia supern…
HS 0943+1404, a true intermediate polar
P. Rodriguez-Gil, B. T. Gaensicke, H. -J. Hagen +7
We have identified a new intermediate polar, HS 0943+1404, as part of our ongoing search for cataclysmic variables in the Hamburg Quasar Survey. The orbital and white dwarf spin pe…
Detection of the white dwarf and the secondary star in the new SU UMa dwarf nova HS 2219+1824
P. Rodriguez-Gil, B. T. Gaensicke, H. -J. Hagen +4
We report the discovery of a new, non-eclipsing SU UMa-type dwarf nova, HS 2219+1824. Photometry obtained in quiescence (V ~ 17.5) reveals a double-humped light curve from which we…
Time-resolved photometry and spectroscopy of the new deeply-eclipsing SW Sextantis star HS 0728+6738
P. Rodriguez-Gil, B. T. Gaensicke, H. Barwig +2
We present time-resolved optical spectroscopy and photometry, and far-ultraviolet spectroscopy of HS 0728+6738, a cataclysmic variable discovered in the Hamburg Quasar Survey. We s…
