    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...
  • Publication
    Internal reddening of H II-regions and HH-objects, with special reference to NGC 896 (W3)
    The effect of scattering by dust internal to H II regions on their spectral characteristics has been studied on the basis of simple analytical models, for...
  • Publication
    Internal rotation of 13 low-mass low-luminosity red giants in the Kepler field
    Context. The Kepler space telescope has provided time series of red giants of such unprecedented quality that a detailed asteroseismic analysis becomes possible...
  • Publication
    Internal rotation of Milky Way dwarf spheroidal satellites with Gaia Early Data Release 3
    We present an analysis of the kinematics of 14 satellites of the Milky Way (MW). We use proper motions (PMs) from the Gaia Early Data Release 3 (EDR3) and line...
  • Publication
    Internal turbulence, viriality, and density bounding of the most luminous H II regions in the spiral galaxy M 100
    We present TAURUS Fabry-Perot velocity data in Hα emission of the disc of the grand design spiral M 100 (NGC 4321). We have studied the emission spectra of the...
  • Publication
    Internetwork magnetic field distribution from simultaneous 1.56 μm and 630 nm observations
    Aims:We study the contradictory magnetic field strength distributions retrieved from independent analyses of spectropolarimetric observations in the near...
  • Publication
    Internight and intranight variations in the wavelength dependent polarization of OJ 287
    Simultaneous UBVRI photopolarimetric observations of the highly variable BL Lac object OJ 287 have been obtained on six nights. The polarization and position...
  • Publication
    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...
