  • VISIR/VLT observations of brown dwarfs in Upper Scorpius

    We present mid-IR observations of a sample of very low-mass stars and brown dwarfs in the Upper Scorpius association. The main goal of these observations is to derive the disk frequency and the disk properties of the sample in order to shed light on brown dwarf formation theories. The observations have been performed with VISIR at the Very Large

  • Visual Determination of the Mean Effective Chromospheric Thickness

    IN the course of taking submillimetre chromospheric data from Concorde 001 during the eclipse of June 30 (ref. 1), it proved possible to record information on the visual thickness of the chromosphere which is accurate enough to merit reporting. During an eclipse viewed conventionally from a stationary site on the ground, the precise time at which

  • VLT FORS2 optical imaging and spectroscopy of nine luminous type 2 AGN at 0.3 < z < 0.6 - I. Ionized gas nebulae

    We present optical imaging and long slit spectroscopic observations of nine luminous type 2 active galactic nuclei (AGN) within the redshift range 0.3

  • VLT/FLAMES spectroscopy of red giant branch stars in the Fornax dwarf spheroidal galaxy

    Context. Fornax is one of the most massive dwarf spheroidal galaxies in the Local Group. The Fornax field star population is dominated by intermediate age stars but star formation was going on over almost its entire history. It has been proposed that Fornax experienced a minor merger event. Aims: Despite recent progress, only the high metallicity

  • VLT/FORS spectroscopy of faint cataclysmic variables discovered by the Sloan Digital Sky Survey

    We present medium-resolution VLT/FORS2 spectroscopy of six cataclysmic variables (CVs) discovered by the Sloan Digital Sky Survey (SDSS). We determine orbital periods for SDSSJ023322.61+005059.5 (96.08 +/- 0.09min), SDSSJ091127.36+084140.7 (295.74 +/- 0.22min), SDSSJ103533.02+055158.3 (82.10 +/- 0.09min) and SDSSJ121607.03+052013.9 (most likely 98

  • WASP-92b, WASP-93b and WASP-118b: three new transiting close-in giant planets

    We present the discovery of three new transiting giant planets, first detected with the WASP telescopes, and establish their planetary nature with follow up spectroscopy and ground-based photometric light curves. WASP-92 is an F7 star, with a moderately inflated planet orbiting with a period of 2.17 d, which has Rp = 1.461 ± 0.077RJ and Mp = 0.805
