    In-depth characterization of the Kepler-10 three-planet system with HARPS-N radial velocities and Kepler transit timing variations
    The old G3V star Kepler-10 is known to host two transiting planets, the ultra-short-period super-Earth Kepler-10 b (P b = 0.837 d; R b = 1.47 R ⊕) and the long...

    Inelastic e+Mg collision data and its impact on modelling stellar and supernova spectra
    Results of calculations for inelastic e+Mg effective collision strengths for the lowest 25 physical states of Mg i (up to 3s6p1P), and thus 300 transitions...

    Inference of electric currents in the solar photosphere
    Context. Despite their importance, routine and direct measurements of electric currents, j, in the solar atmosphere have generally not been possible. Aims: We...

    Inference of magnetic field strength and density from damped transverse coronal waves
    A classic application of coronal seismology uses transverse oscillations of waveguides to obtain estimates of the magnetic field strength. The procedure...

    Inference of magnetic fields in the very quiet Sun
    Context. Over the past 20 yr, the quietest areas of the solar surface have revealed a weak but extremely dynamic magnetism occurring at small scales (
  • Publication
    Inference of the chromospheric magnetic field orientation in the Ca ii 8542 Å line fibrils
    Context. Solar chromospheric fibrils, as observed in the core of strong chromospheric spectral lines, extend from photospheric field concentrations suggesting...

    Inferring physical parameters in solar prominence threads
    Context. High resolution observations have permitted the resolution of solar prominences/filaments into sets of threads/fibrils. However, the values of the...

    Inflection point in the power spectrum of stellar brightness variations. II. The Sun
    Context. Young and active stars generally have regular, almost sinusoidal, patterns of variability attributed to their rotation, while the majority of older and...
  • Publication
    Inflection point in the power spectrum of stellar brightness variations. III. Facular versus spot dominance on stars with known rotation periods
    Context. Stellar rotation periods can be determined by observing brightness variations caused by active magnetic regions transiting visible stellar disk as the...
