    Gradients of chemical abundances in the Milky Way from H II regions: distances derived from Gaia EDR3 parallaxes and temperature inhomogeneities
    We present a reassessment of the radial abundance gradients of He, C, N, O, Ne, S, Cl, and Ar in the Milky Way using the deep optical spectra of 42 H II regions...

    Gran Telescopio Canarias observations of an overdense region of Lyman α emitters at z = 6.5
    We present the results of our search near the end of the Reionization Epoch for faint galaxies. This has been done using very deep OSIRIS images obtained at the...

    Gran Telescopio Canarias OSIRIS transiting exoplanet atmospheric survey: detection of potassium in XO-2b from narrowband spectrophotometry
    We present Gran Telescopio Canarias (GTC) optical transit narrowband photometry of the hot-Jupiter exoplanet XO-2b using the OSIRIS instrument. This unique...

    Grand Design and Flocculent Spirals in the Spitzer Survey of Stellar Structure in Galaxies (S4G)
    Spiral arm properties of 46 galaxies in the Spitzer Survey of Stellar Structure in Galaxies (S4G) were measured at 3.6 μm, where extinction is small and the old...
  • Publication
    Granulation and magnetism in the solar atmosphere.
    The properties of the photosphere in magnetic and non magnetic regions, at two levels in the solar atmosphere, have been studied, using two virtually...
  • Publication
    Granulation deformation near and in sunspot regions
    High-resolution white-light pictures are analyzed to study the differences between the granular size near sunspot penumbrae and in light-bridges presenting...
  • Publication
    Granulation in K-type dwarf stars. I. Spectroscopic observations
    Aims: We seek to detect and quantify the effects of surface convection (granulation) on the line spectra of K-dwarfs as a first step towards a rigorous testing...
  • Publication
    Granulation in K-type dwarf stars. II. Hydrodynamic simulations and 3D spectrum synthesis
    Aims: To explore the impact of surface inhomogeneities on stellar spectra, granulation models need to be computed. Ideally, the most fundamental characteristics...
  • Publication
    Granulation in Red Giants: Observations by the Kepler Mission and Three-dimensional Convection Simulations
    The granulation pattern that we observe on the surface of the Sun is due to hot plasma rising to the photosphere where it cools down and descends back into the...
