    Line Formation Theory for the Multiterm Atom with Hyperfine Structure in a Magnetic Field
    Within the framework of the quantum theory of polarized line formation, in the limit of complete frequency redistribution and of the collisionless regime, we...

    Line Shape Effects on Intensity Measurements of Solar Features: Brightness Correction to SOHO MDI Continuum Images
    Continuum intensity observations obtained with the Michelson Doppler Imager (MDI) on board the SOHO mission provide long time series of filtergrams that are...

    LINER-like Extended Nebulae in ULIRGs: Shocks Generated by Merger-Induced Flows
    In this work we studied the two-dimensional ionization structure of the circumnuclear and extranuclear regions in a sample of six low-z ultraluminous infrared...

    Lithium Abundances in nearby FGK Dwarf and Subgiant Stars: Internal Destruction, Galactic Chemical Evolution, and Exoplanets
    We derive atmospheric parameters and lithium abundances for 671 stars and include our measurements in a literature compilation of 1381 dwarf and subgiant stars...

    Local and Global Gas Metallicity versus Stellar Age Relation in MaNGA Galaxies
    The search for new global scaling relations linking the physical properties of galaxies has a fundamental interest. Furthermore, their recovery from spatially...

    Local Tadpole Galaxies
    Tadpole galaxies have a giant star-forming region at the end of an elongated intensity distribution. Here we use Sloan Digital Sky Survey data to determine the...

    Local Tadpole Galaxies: Dynamics and Metallicity
    Tadpole galaxies, with a bright peripheral clump on a faint tail, are morphological types unusual in the nearby universe but very common early on. Low mass...

    Long Characteristics versus Short Characteristics in 3D Radiative Transfer Simulations of Polarized Radiation
    We compare maps of scattering polarization signals obtained from three-dimensional (3D) radiation transfer calculations in a magnetoconvection model of the...

    Long-term Monitoring, Time Delay, and Microlensing in the Gravitational Lens System Q0142-100
    We present 12 yr of monitoring of the gravitational lens Q0142-100 from the Teide Observatory. The data, taken from 1999 to 2010, comprise 105 observing nights...
