A large, long-lived structure near the trojan L5 point in the post common-envelope binary SDSS J1021+1744
P. Irawati, A. Richichi, M. C. P. Bours +8
SDSS J1021+1744 is a detached, eclipsing white dwarf / M dwarf binary discovered in the Sloan Digital Sky Survey. Outside the primary eclipse, the light curves of such systems are…
Doppler-imaging of the planetary debris disc at the white dwarf SDSS J122859.93+104032.9
Christopher J. Manser, Boris T. Gaensicke, Thomas R. Marsh +6
Debris discs which orbit white dwarfs are signatures of remnant planetary systems. We present twelve years of optical spectroscopy of the metal-polluted white dwarf SDSS J1228+1040…
The Composition Of A Disrupted Extrasolar Planetesimal At SDSS J0845+2257 (Ton 345)
David J. Wilson, Boris T. Gaensicke, Detlev Koester +4
We present a detailed study of the metal-polluted DB white dwarf SDSS J0845+2257 (Ton 345). Using high-resolution HST/COS and VLT spectroscopy, we have detected hydrogen and eleven…
PHL 1445: An eclipsing cataclysmic variable with a substellar donor near the period minimum
M. J. McAllister, S. P. Littlefair, I. Baraffe +14
We present high-speed, three-colour photometry of the eclipsing dwarf nova PHL 1445, which, with an orbital period of 76.3 min, lies just below the period minimum of ~82 min for ca…
The first pre-supersoft X-ray binary
S. G. Parsons, M. R. Schreiber, B. T. Gansicke +8
We report the discovery of an extremely close white dwarf plus F dwarf main-sequence star in a 12 hour binary identified by combining data from the RAdial Velocity Experiment (RAVE…
The First Science Results from SPHERE: Disproving the Predicted Brown Dwarf around V471 Tau
A. Hardy, M. R. Schreiber, S. G. Parsons +10
Variations of eclipse arrival times have recently been detected in several post common envelope binaries consisting of a white dwarf and a main sequence companion star. The general…
HST+COS spectra of the double white dwarf CSS 41177 place the secondary inside the pulsational instability strip
Madelon Bours, Thomas Marsh, Boris Gaensicke +1
We present Hubble Space Telescope + Cosmic Origins Spectrograph (HST+COS) data of the eclipsing double white dwarf binary CSS 41177. Due to the temperature difference between the t…
