    The GRB 060218/SN 2006aj event in the context of other gamma-ray burst supernovae
    The supernova SN 2006aj associated with GRB 060218 is the second-closest GRB-SN observed to date (z=0.033). We present Very Large Telescope, Liverpool Telescope...

    The GTC exoplanet transit spectroscopy survey . I. OSIRIS transmission spectroscopy of the short period planet WASP-43b<xref ref-type="fn" rid="FN1"><xref ref-type="fn" rid="FN2">⋆
    Aims: In this work, we use long-slit spectroscopy observations of a transit event of the close-in orbiting planet WASP-43b (Mp = 2.034 MJup, Rp = 1.036 RJup) in...

    The GTC exoplanet transit spectroscopy survey . VII. An optical transmission spectrum of WASP-48b
    Context. Transiting planets offer an excellent opportunity for characterizing the atmospheres of extrasolar planets under very different conditions from those...

    The GTC exoplanet transit spectroscopy survey. II. An overly large Rayleigh-like feature for exoplanet TrES-3b
    Aims: We search for Rayleigh scattering and K and Na absorption signatures from the atmosphere of TrES-3b using ground-based transmission spectroscopy covering...

    The GTC exoplanet transit spectroscopy survey. III. No asymmetries in the transit of CoRoT-29b
    Context. The launch of the exoplanet space missions obtaining exquisite photometry from space has resulted in the discovery of thousands of planetary systems...

    The GTC exoplanet transit spectroscopy survey. IV. Confirmation of the flat transmission spectrum of HAT-P-32b
    We observed the hot Jupiter HAT-P-32b (also known as HAT-P-32Ab) to determine its optical transmission spectrum by measuring the wavelength-dependent, planet-to...

    The GTC exoplanet transit spectroscopy survey. IX. Detection of haze, Na, K, and Li in the super-Neptune WASP-127b
    Exoplanets with relatively clear atmospheres are prime targets for detailed studies of chemical compositions and abundances in their atmospheres. Alkali metals...

    The GTC exoplanet transit spectroscopy survey. V. A spectrally-resolved Rayleigh scattering slope in GJ 3470b
    Aims: As a sub-Uranus-mass low-density planet, GJ 3470b has been found to show a flat featureless transmission spectrum in the infrared and a tentative Rayleigh...

    The GTC exoplanet transit spectroscopy survey. VI. Detection of sodium in WASP-52b's cloudy atmosphere
    We report the first detection of sodium absorption in the atmosphere of the hot Jupiter WASP-52b. We observed one transit of WASP-52b with the low-resolution...
