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...
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...
