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…
