Target entity: Coronagraphic High Angular Resolution Imaging Spectrograph
Context triple: [CHARIS, fullName, Coronagraphic High Angular Resolution Imaging Spectrograph]
  • A. Large Angle and Spectrometric Coronagraph
    The Large Angle and Spectrometric Coronagraph (LASCO) is a space-based solar coronagraph instrument that images the Sun’s outer atmosphere to study coronal mass ejections and other solar phenomena.
  • B. Coronagraph Instrument
    The Coronagraph Instrument is a high-contrast imaging and spectroscopy tool on the Nancy Grace Roman Space Telescope designed to directly observe and characterize exoplanets and faint circumstellar material near bright stars.
  • C. Spectro-Polarimetric High-contrast Exoplanet REsearch
    Spectro-Polarimetric High-contrast Exoplanet REsearch (SPHERE) is a high-performance instrument on the Very Large Telescope designed to directly image and characterize exoplanets and circumstellar disks using advanced adaptive optics and polarimetry.
  • D. Metis coronagraph
    Metis coronagraph is a specialized telescope instrument designed to block the Sun’s bright disk so it can image and study the faint outer solar corona in visible and ultraviolet light.
  • E. Lyot coronagraphs
    Lyot coronagraphs are optical devices used in telescopes to block out the bright light of a star so that faint nearby objects, such as exoplanets or circumstellar disks, can be imaged.
  • F. None of above. chosen
  • G. Unsure - the case is ambiguous/there is not enough information to decide.
