    A New Technique for Performing Two-Dimensional Spectroscopy of Objects of Large Dynamic Range: The Binary System HD 167605 A+B
    We present a new technique for performing two-dimensional (integral-field) spectroscopy of objects with a large range in intensity. It is based on the...

    A New Technique to Measure Magnetic Field Strength in Active Stars
    We explore the use of the flux difference between the lines Fe 15250 Å and Fe 15247 Å as a technique to measure photospheric magnetic fields in late-type stars...

    A new tidal scenario for double bar formation
    Double bars make up a significant fraction of barred galaxies. We propose a new formation scenario for double bars that involves tidal interactions. We...

    A New View of the Dwarf Spheroidal Satellites of the Milky Way from VLT FLAMES: Where Are the Very Metal-poor Stars?
    As part of the Dwarf galaxies Abundances and Radial-velocities Team (DART) program, we have measured the metallicities of a large sample of stars in four nearby...

    A New View of the Solar Interface Region from the Interface Region Imaging Spectrograph (IRIS)
    The Interface Region Imaging Spectrograph (IRIS) has been obtaining near- and far-ultraviolet images and spectra of the solar atmosphere since July 2013. IRIS...

    A new visual - near-infrared diagnostic to estimate the metallicity of cluster and field dwarf stars
    We present a theoretical calibration of a new metallicity diagnostic based on the Strömgren index m1 and on visual - near-infrared (NIR) colors to estimate the...
