Target entity: Large Angle and Spectrometric Coronagraph
Context triple: [SOHO, hasInstrument, Large Angle and Spectrometric Coronagraph]
  • A. 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.
  • B. 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.
  • C. 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.
  • D. JWST coronagraphy with MIRI
    JWST coronagraphy with MIRI is an observing mode of the James Webb Space Telescope’s Mid-Infrared Instrument that uses specialized masks and optics to block starlight and enable high-contrast imaging of faint structures such as exoplanets and circumstellar disks in the mid-infrared.
  • E. 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.
  • F. None of above. chosen
  • G. Unsure - the case is ambiguous/there is not enough information to decide.
