    Improved High-resolution Fast Imager
    The improved High-resolution Fast Imager (HiFI+) is a multiwavelength imaging filtergraph, which was commissioned at the GREGOR solar telescope at Observatorio...

    Improved Hubble Space Telescope proper motions for Tycho-G and other stars in the remnant of Tycho's Supernova 1572
    With archival and new Hubble Space Telescope observations, we have refined the space-velocity measurements of the stars in the central region of the remnant of...

    Improved hydrodynamic pulsation models for the pulsating extreme helium star V652 Herculis
    New non-linear hydrodynamic models have been constructed to simulate the radial pulsations observed in the extreme helium star V652 Her. These use a finer...

    Improved method of hydrous mineral detection by latitudinal distribution of 0.7-μm surface reflectance absorption on the asteroid Ryugu
    Global multiband images of the C-type asteroid (162173) Ryugu were obtained by the optical navigation camera telescope (ONC-T) onboard Hayabusa2. The 0.7-μm...

    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...
  • Publication
    Improved near optimal angular quadratures for polarised radiative transfer in 3D MHD models
    Accurate angular quadratures are crucial for the numerical solution of three-dimensional (3D) radiative transfer problems, especially when the spectral line...
  • Publication
    Improved NLTE profiles of He II lines in hot stars including their overlap with hydrogen
    The accelerated Lambda iteration method is used to obtain better theoretical profiles of He II in hot stars by considering more levels and Stark broadening in...
  • Publication
    Improved non-LTE Balmer-line profiles for hot stars
    Improved non-LTE line formation calculations for hydrogen in O-stars are presented. The calculations are carried out by means of the method recently developed...
  • Publication
    Improved Search of Principal Component Analysis Databases for Spectro-polarimetric Inversion
    We describe a simple technique for the acceleration of spectro-polarimetric inversions based on principal component analysis (PCA) of Stokes profiles. This...
