    Stars and brown dwarfs in the σ Orionis cluster. IV. IDS/INT and OSIRIS/GTC spectroscopy and Gaia DR2 astrometry
    Context. Only a few open clusters are as important for the study of stellar and substellar objects, and their formation and evolution, as the young σ Orionis...

    Stars and gas in the inner parts of galaxies seen in SAURON integral field observations
    We give two examples of spiral galaxies that show non-circular gas motions in the inner kiloparsecs, from SAURON integral field spectroscopy. We use harmonic...
  • Publication
    Stars approaching the substellar limit in the α Persei open cluster.
    We present intermediate dispersion optical spectroscopy for seven very low-mass stars in the α Per open cluster with spectral types between M3 and M6, including...
  • Publication
    Stars Within the Large Magellanic Cloud as Potential Lenses for Observed Microlensing Events
    MASSIVE compact objects in the Galactic halo, known as MACHOs, have been postulated as the origin of a substantial fraction of the 'dark matter' known to exist...
  • Publication
    Starspots on the fastest rotators in the β Pictoris moving group
    Aims: We carried out high-resolution spectroscopy and BV(I)C photometric monitoring of the two fastest late-type rotators in the nearby β Pictoris moving group...
  • Publication
    Static telescope aberration measurement using lucky imaging techniques
    A procedure has been developed to compute static aberrations once the telescope PSF has been measured with the lucky imaging technique, using a nearby star...
  • Publication
    Statistical analysis of Galactic globular cluster type properties
    The analysis of pseudo-colour diagrams, the so-called chromosome maps, of Galactic globular clusters (GCs) permits to classify them into type I and type II...

  • Publication
    Statistical Analysis of the very Quiet Sun Magnetism
    The behavior of the observed polarization amplitudes with spatial resolution is a strong constraint on the nature and organization of solar magnetic fields...
