    Observations of two superfast rotator NEAs: 2021 NY<SUB>1</SUB> and 2022 AB
    In the framework of the visible NEAs observations survey (ViNOS) that uses several telescopes at the Canary Islands observatories since 2018, we observed two...

    Observations, compositional, and physical characterization of near-Earth and Mars-crosser asteroids from a spectroscopic survey
    Aims: We analyse a significantly large sample of spectroscopic data to provide a compositional characterization of the near-Earth asteroid population. We...

    OCCASO - II. Physical parameters and Fe abundances of red clump stars in 18 open clusters
    Open clusters have long been used to study the chemodynamical evolution of the Galactic disc. This requires a homogeneously analysed sample covering a wide...

    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...

    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...

    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...
