    A Whole Earth Telescope campaign on the pulsating subdwarf B binary system PG 1336-018 (NY Vir)
    We present results from a multisite (`Whole Earth Telescope') photometric campaign on PG 1336-018, the close eclipsing binary system containing a pulsating...
  • Publication
    A wide deep infrared look at the Pleiades with UKIDSS: new constraints on the substellar binary fraction and the low-mass initial mass function
    We present the results of a deep wide-field near-infrared survey of 12 deg2 of the Pleiades conducted as part of the United Kingdom Infrared Telescope (UKIRT)...
  • Publication
    A wide star-black-hole binary system from radial-velocity measurements
    All stellar-mass black holes have hitherto been identified by X-rays emitted from gas that is accreting onto the black hole from a companion star. These systems...
  • Publication
    A wide-area view of the Phoenix dwarf galaxy from Very Large Telescope/FORS imaging
    We present results from a wide-area photometric survey of the Phoenix dwarf galaxy, one of the rare dwarf irregular/dwarf spheroidal transition-type galaxies...
  • Publication
    A Wide-orbit Exoplanet OGLE-2012-BLG-0838Lb
    We present the discovery of a planet on a very wide orbit in the microlensing event OGLE-2012-BLG-0838. The signal of the planet is well separated from the main...
  • Publication
    A wiggling filamentary jet at the origin of the blazar multi-wavelength behaviour
    Context. Blazars are beamed active galactic nuclei (AGNs) known for their strong multi-wavelength variability on timescales ranging from years down to minutes...
  • Publication
    A Wildly Flickering Jet in the Black Hole X-Ray Binary MAXI J1535–571
    We report on the results of optical, near-infrared (NIR), and mid-infrared observations of the black hole X-ray binary candidate (BHB) MAXI J1535–571 during its...
  • Publication
    A young binary brown dwarf in the R-CrA star formation region
    We present imaging and spectroscopic observations with HST (WFPC2, ACS/HRC and STIS), VLT (FORS2) and Keck (HIRES) of the dM 8 ultra-cool dwarf DENIS-P J185950...
  • Publication
    A young spectroscopic binary in a quintuple system part of the Local Association
    Context. Double-lined spectroscopic (SB2) binaries allow us to obtain a direct determination of the masses of their components, which is essential to test...
