    Analysing the evolution of the thermal and magnetic properties of an X-class flare in the low solar atmosphere
    We analysed the evolution of the spatial distribution and stratification of the physical parameters of the atmosphere of an X-class flare in the photosphere and...

    Analysis and calibration of CaII triplet spectroscopy of red giant branch stars from VLT/FLAMES observations
    We demonstrate that low-resolution CaII triplet (CaT) spectroscopic estimates of the overall metallicity ([Fe/H]) of individual red giant branch (RGB) stars in...
  • Publication
    Analysis of a spatially deconvolved solar pore
    Solar pores are active regions with large magnetic field strengths and apparent simple magnetic configurations. Their properties resemble the ones found for the...

    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...
