Cyclical period changes in HT Cas: a clear difference between systems above and below the period gap
B. W. Borges, R. Baptista, C. Papadimitriou +1
We report the identification of cyclical changes in the orbital period of the eclipsing cataclysmic variable HT Cas. We measured new white dwarf mid-eclipse timings and combined wi…
HS1857+5144: A hot and young pre-cataclysmic variable
A. Aungwerojwit, B. T. Gaensicke, P. Rodriguez-Gil +5
We report the discovery of a new white dwarf/M dwarf binary, HS1857+5144, identified in the Hamburg Quasar Survey (HQS). Time-resolved optical spectroscopy and photometry were carr…
SW Sextantis stars: the dominant population of CVs with orbital periods between 3-4 hours
P. Rodriguez-Gil, B. T. Gaensicke, H. -J. Hagen +15
[Abridged] We present time-series optical photometry of five new CVs identified by the Hamburg Quasar Survey. The eclipses observed in HS 0129+2933, HS 0220+0603, and HS 0455+8315…
