    Analysis of γ Doradus and δ Scuti stars observed by Kepler
    The Kepler spacecraft observed over 2000 faint stars that were part of our Guest Observer proposals. The stars were selected from the Kepler Input Catalog (KIC)...

    Analytical Calculation of Stokes Profiles of Rotating Stellar Magnetic Dipole
    The observation of the polarization emerging from a rotating star at different phases opens up the possibility to map the magnetic field in the stellar surface...
  • Publication
    Analytical maximum likelihood estimation of stellar magnetic fields
    The polarized spectrum of stellar radiation encodes valuable information on the conditions of stellar atmospheres and the magnetic fields that permeate them. In...

    Anomalous Circular Polarization Profiles in the He I 1083.0 nm Multiplet from Solar Spicules
    We report Stokes vector observations of solar spicules and a prominence in the He I 1083 nm multiplet carried out with the Tenerife Infrared Polarimeter. The...

    Anomalously Low-metallicity Regions in MaNGA Star-forming Galaxies: Accretion Caught in Action?
    We use data from 1222 late-type star-forming galaxies in the SDSS IV Mapping Nearby Galaxies at Apache Point Observatory survey to identify regions in which the...

    Another shipment of six short-period giant planets from TESS
    We present the discovery and characterization of six short-period, transiting giant planets from NASA's Transiting Exoplanet Survey Satellite (TESS) -- TOI-1811...

    Aperture corrections for disk galaxy properties derived from the CALIFA survey. Balmer emission lines in spiral galaxies
    This work investigates the effect of the aperture size on derived galaxy properties for which we have spatially-resolved optical spectra. We focus on some...

    APOGEE Kinematics. I. Overview of the Kinematics of the Galactic Bulge as Mapped By APOGEE
    We present the stellar kinematics across the Galactic bulge and into the disk at positive longitudes from the SDSS-III APOGEE spectroscopic survey of the Milky...
