    OCCASO - III. Iron peak and α elements of 18 open clusters. Comparison with chemical evolution models and field stars
    The study of open-cluster chemical abundances provides insights on stellar nucleosynthesis processes and on Galactic chemo-dynamical evolution. In this paper we...
  • Publication
    On Spectropolarimetric Measurements with Visible Lines
    The ability of new instruments for providing accurate inferences of vector magnetic fields and line-of-sight velocities of the solar plasma depends a great deal...
  • Publication
    On the Connection of the Apparent Proper Motion and the VLBI Structure of Compact Radio Sources
    Many of the compact extragalactic radio sources that are used as fiducial points to define the celestial reference frame are known to have proper motions...
  • Publication
    On the constraining observations of the dark GRB 001109 and the properties of a z = 0.398 radio selected starburst galaxy contained in its error box
    We present optical and NIR (near infrared) follow up observations of the GRB 001109 from 1 to 300 days after the burst. No transient emission was found at these...

    On the elusive detection of O-type stars close to the ZAMS: the empirical birthline of massive stars
    In this contribution we present the results from a 1 homogeneous quantitative spectroscopic analysis of ∼400 Galactic O-type stars targeted by the IACOB and OWN...

    On the estimation of galaxy structural parameters: the Sérsic model
    This paper addresses some questions which have arisen from the use of the Sérsic r1/n law in modelling the luminosity profiles of early-type galaxies. The first...

    On the HU Aquarii planetary system hypothesis
    In this paper, we investigate the eclipse timing of the polar binary HU Aquarii that has been observed for almost two decades. Recently, Qian et al. attributed...

    On the interpolation of model atmospheres and high-resolution synthetic stellar spectra
    We present tests carried out on optical and infrared stellar spectra to evaluate the accuracy of different types of interpolation. Both model atmospheres and...

    On the Inversion of Stokes Profiles with Local Stray-light Contamination
    Obtaining the magnetic properties of non-resolved structures in the solar photosphere is always challenging and problems arise because the inversion is carried...
