    Impact of opacity effects on chromospheric oscillations inferred from NLTE inversions
    Context. Spectropolarimetric inversions are a fundamental tool for diagnosing the solar atmosphere. Chromospheric inferences rely on the interpretation of...

    Improved models for the near-Earth asteroids (2100) Ra-Shalom, (3103) Eger, (12711) Tukmit, and (161989) Cacus
    We present 24 new dense light curves of the near-Earth asteroids (3103) Eger, (161989) Cacus, (2100) Ra-Shalom, and (12711) Tukmit, obtained with the Instituto...

    Improving light curve parameters of exoplanets based on TESS data
    We revise parameters of four transiting hot Jupiter planets discovered by ground-based surveys. We use follow-up observations carried by TESS mission together...

    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 (

    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...

    Influence of phase-diversity image reconstruction techniques on circular polarization asymmetries
    Context. Full Stokes filter-polarimeters are key instruments for investigating the rapid evolution of magnetic structures on the solar surface. To this end, the...

    Infrared and Optical Polarimetry around the Low-mass Star-forming Region NGC 1333 IRAS 4A
    We performed J- and R-band linear polarimetry with the 4.2 m William Herschel Telescope at the Observatorio del Roque de los Muchachos and with the 1.6 m...

    Infrared Extinction in the Inner Milky Way through Red Clump Giants
    While the shape of the extinction curve in the infrared is considered to be set and the extinction ratios between infrared bands are usually taken to be...

    Infrared Laboratory Oscillator Strengths of Fe I in the H-band
    We report experimental oscillator strengths for 28 infrared Fe I transitions, for which no previous experimental values exist. These transitions were selected...
