Post-common-envelope binaries from SDSS. IX: Constraining the common-envelope efficiency
Context. Reconstructing the evolution of post-common-envelope binaries (PCEBs) consisting of a white dwarf and a main-sequence star can constrain current prescriptions of common-envelope (CE)Expand

Post common envelope binaries from SDSS - XI. The white dwarf mass distributions of CVs and pre-CVs
Context. We have known for a long time that many of the measured white dwarf (WD) masses in cataclysmic variables (CVs) significantly exceed the mean mass of single WDs. This was thought to beExpand

A Gaia Data Release 2 catalogue of white dwarfs and a comparison with SDSS
We present a catalogue of white dwarf candidates selected from the second data release of Gaia (DR2). We used a sample of spectroscopically confirmed white dwarfs from the Sloan Digital Sky SurveyExpand

The second data release of the INT Photometric Hα Survey of the Northern Galactic Plane (IPHAS DR2)
The INT/WFC Photometric Hα Survey of the Northern Galactic Plane (IPHAS) is a 1800 deg2 imaging survey covering Galactic latitudes |b| < 5° and longitudes l = 30°–215° in the r, i, and Hα filtersExpand

The frequency of planetary debris around young white dwarfs
Context. Heavy metals in the atmospheres of white dwarfs are thought in many cases to be accreted from a circumstellar debris disk, which was formed by the tidal disruption of a rocky planetary bodyExpand

Orbital period variations in eclipsing post-common-envelope binaries
We present high-speed ULTRACAM photometry of the eclipsing post-common-envelope binaries DE CVn, GK Vir, NN Ser, QS Vir, RR Cae, RX J2130.6+4710, SDSS 0110+1326 and SDSS 0303+0054 and use these dataExpand

Precise mass and radius values for the white dwarf and low mass M dwarf in the pre‐cataclysmic binary NN Serpentis
Using the high resolution Ultraviolet and Visual Echelle Spectrograph (UVES) mounted on the Very Large Telescope in combination with photometry from the high-speed CCD camera ULTRACAM, we deriveExpand

Post common envelope binaries from SDSS. XII : the orbital period distribution
Context. The complexity of the common-envelope phase and of magnetic stellar wind braking currently limits our understanding of close binary evolution. Because of their intrinsically simpleExpand

Initial data release of the Kepler-INT survey
This paper describes the first data release of the Kepler-INT Survey (KIS), that covers a 116 deg2 region of the Cygnus and Lyra constellations. The Kepler field is the target of the most intensiveExpand

Cataclysmic Variables from SDSS VII. The Seventh Year (2006)
Coordinates, magnitudes, and spectra are presented for 39 cataclysmic variables (CVs) found in Sloan Digital Sky Survey (SDSS) spectra that were primarily obtained in 2006. Of these, 13 were CVsExpand
