    Inversions of L12-2 IMaX data of an emerging flux mantle
    We present the analysis of a flux emergence event observed with the IMaX magnetograph flown aboard the SUNRISE balloon. IMaX took a 15' sequence with cadence of...

    Inversions of synthetic umbral flashes: a selection of wavelength sampling
    Context. Imaging spectrographs are popular instruments used to obtain solar data. They record quasi-monochromatic images at selected wavelength positions. By...

    Inversions of synthetic umbral flashes: Effects of scanning time on the inferred atmospheres
    Context. The use of instruments that record narrowband images at selected wavelengths is a common approach in solar observations. They allow scanning of a...

    Investigating the architecture and internal structure of the TOI-561 system planets with CHEOPS, HARPS-N, and TESS
    We present a precise characterization of the TOI-561 planetary system obtained by combining previously published data with TESS and CHEOPS photometry, and a new...

    Investigating the visible phase-curve variability of 55 Cnc e★
    Context. 55 Cnc e is an ultra-short period super-Earth transiting a Sun-like star. Previous observations in the optical range detected a time-variable flux...

    Ionized calcium in the atmospheres of two ultra-hot exoplanets WASP-33b and KELT-9b
    Ultra-hot Jupiters are emerging as a new class of exoplanets. Studying their chemical compositions and temperature structures will improve our understanding of...

    Ionized gas kinematics of galaxies in the CALIFA survey. I. Velocity fields, kinematic parameters of the dominant component, and presence of kinematically distinct gaseous systems
    Context. Ionized gas kinematics provide important clues to the dynamical structure of galaxies and hold constraints to the processes driving their evolution...

    Is binning always sinning? The impact of time-averaging for exoplanet phase curves
    We explore how finite integration time or temporal binning can affect the analysis of exoplanet phase curves. We provide analytical formulae to account for this...

    Is the activity level of HD 80606 influenced by its eccentric planet?
    Aims: Several studies suggest that the activity level of a planet-host star can be influenced by the presence of a close-by orbiting planet. Moreover, the...
