    Study of an active region prominence using spectropolarimetric data in the He I D<SUB>3</SUB> multiplet
    Context. Prominences are cool overdensities of plasma supported by magnetic fields that levitate in the solar corona. The physical characterization of these...

    Study of KIC 8561221 observed by Kepler: an early red giant showing depressed dipolar modes
    Context. The continuous high-precision photometric observations provided by the CoRoT and Kepler space missions have allowed us to understand the structure and...
  • Publication
    Study of p-mode excitation and damping rate variations from IRIS++ observations
    11 years of low degree helioseismic data collected by the IRIS++ network (International Research of the Interior of the Sun) have been analyzed. The epoch...

    Study of star-forming galaxies in SDSS up to redshift 0.4. I. Metallicity evolution
    Context: The chemical composition of the gas in galaxies over cosmic time provides a very important tool for understanding galaxy evolution. Although there are...
  • Publication
    Study of star-forming galaxies in SDSS up to redshift 0.4. II. Evolution from the fundamental parameters: mass, metallicity and star formation rate
    Context. To understand the formation and evolution of galaxies, it is important to have a full comprehension of the role played by metallicity, star formation...

    Study of stellar populations in the bulges of barred galaxies
    Aims: We wish to determine the influence of bars on the building of galaxy bulges through analysis of ages and metallicities derived from stellar absorption...
  • Publication
    Study of the excitation of large-amplitude oscillations in a prominence by nearby flares
    Context. Large-amplitude oscillations are a common occurrence in solar prominences. These oscillations are triggered by energetic phenomena such as jets and...

    Study of the GeV to TeV morphology of the γ Cygni SNR (G 78.2+2.1) with MAGIC and Fermi-LAT. Evidence for cosmic ray escape
    Context. Diffusive shock acceleration (DSA) is the most promising mechanism that accelerates Galactic cosmic rays (CRs) in the shocks of supernova remnants...
