    Intermediate Resolution Near-infrared Spectroscopy of 36 Late M Dwarfs
    We present observations of 36 late M dwarfs obtained with the Keck II/NIRSPEC in the J band at a resolution of ~20,000. We have measured projected rotational...

    Intermediate-mass stars and the origin of the gas-giant planet-metallicity correlation
    Context. Currently, the number of known planets around intermediate-mass stars (1.5 M ⊙ < M ⋆ < 3.5 M ⊙) is rather low. As a consequence, models of planet...

    Internal kinematics and physical properties of HII regions in the Arp 270 system
    We have observed Arp 270 using the GHαFaS Fabry-Perot spectrometer on the 4.2m William Herschel Telescope (La Palma). In the edge-on companion we detect a...

    Internal Proper Motions in the Eskimo Nebula
    We present measurements of internal proper motions at more than 500 positions of NGC 2392, the Eskimo Nebula, based on images acquired with WFPC2 on board the...

    Interpolation of spectra from 3D model atmospheres
    Context. The use of 3D hydrodynamical simulations of stellar surface convection for model atmospheres is computationally expensive. Although these models have...

    Interpretation of HINODE SOT/SP asymmetric Stokes profiles observed in the quiet Sun network and internetwork
    Stokes profiles emerging from the magnetized solar photosphere and observed by SOT/SP aboard the HINODE satellite exhibit a variety of complex shapes. These are...

    Into the storm: diving into the winds of the ultra-hot Jupiter WASP-76 b with HARPS and ESPRESSO
    Context. Despite swift progress in the characterisation of exoplanet atmospheres in composition and structure, the study of atmospheric dynamics has not...

    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...
