  • Publication
    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...
  • Publication
    On the interpretation of the optical spectra of L-type dwarfs
    We present synthetic optical spectra in the red and far-red (640-930 nm) of a sample of field L dwarfs suitably selected to cover this new spectral class, and...
  • Publication
    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...
  • Publication
    On the Inversion of the Scattering Polarization and the Hanle Effect Signals in the Hydrogen Lyα Line
    Magnetic field measurements in the upper chromosphere and above, where the gas-to-magnetic pressure ratio β is lower than unity, are essential for understanding...
  • Publication
    On the Ionizing Continuum in Active Galactic Nuclei: Clues from the Infrared Space Observatory
    The Infrared Space Observatory (ISO) coronal line spectrum of the brightest Seyfert galaxies from the CfA sample is presented and modeled. ISO observations of...
  • Publication
    On the Kinematic Separation of Field and Cluster Stars across the Bulge Globular NGC 6528
    We present deep and precise multi-band photometry of the Galactic bulge globular cluster NGC 6528. The current data set includes optical and near-infrared...
  • Publication
    On The Kinematics of Multiple-Shell Planetary Nebulae. I. Data and Expansion Velocities
    We present spatially resolved echelle spectroscopy, obtained at high spectral resolution, for 15 multiple-shell planetary nebulae. Most exhibit faint detached...
  • Publication
    On the kinematics of the neutron star low mass X-ray binary Cen X-4
    We present the first determination of the proper motion of the neutron star low mass X-ray binary Cen X-4 measured from relative astrometry of the secondary...
