    First simultaneous UBVRI photopolarimetric observations of a sample of normal quasars
    We present what we believe to be the first truly simultaneous UBVRI photopolarimetric results for a sample of eight 'normal' quasars. In five of these quasars...
  • Publication
    First spectroscopic investigation of anomalous Cepheid variables
    Context. Anomalous Cepheids (ACEPs) are intermediate-mass metal-poor pulsators that are mostly discovered in dwarf galaxies of the Local Group. However, recent...

    First stars XI. Chemical composition of the extremely metal-poor dwarfs in the binary CS 22876-032
    Context: Unevolved metal-poor stars constitute a fossil record of the early Galaxy, and can provide invaluable information on the properties of the first...
  • Publication
    First stellar spectroscopy in Leo P
    We present the first stellar spectroscopy in the low-luminosity (MV ˜ -9.3 mag), dwarf galaxy Leo P. Its significantly low oxygen abundance (3% solar) and...
  • Publication
    First survey of phase curves of V-type asteroids
    The V-type asteroids are of major scientific interest as they may sample multiple differentiated planetesimals. Determination of their physical properties is...
  • Publication
    First survey of Wolf-Rayet star populations over the full extension of nearby galaxies observed with CALIFA
    The search of extragalactic regions with conspicuous presence of Wolf-Rayet (WR) stars outside the Local Group is challenging task owing to the difficulty in...
  • Publication
    First T dwarfs in the VISTA Hemisphere Survey
    Aims: The aim of the project is to improve our current knowledge of the density of T dwarfs and the shape of the substellar initial mass function by identifying...
  • Publication
    First tentative detection of anisotropy in the QSO distribution around nearby edge-on spiral galaxies
    Aims:To check whether the polar angle distribution of QSOs around nearby spiral galaxies is isotropic or not. Methods: A statistical analysis of the polar angle...

    First View of the Solar Core from GOLF Acoustic Modes
    After 8 months of nearly continuous measurements the GOLF instrument, aboard SOHO, has detected acoustic mode frequencies of more than 100 modes, extending from...
