Papers on CHIRON

CHIRON is a highly stable cross-dispersed echelle spectrometer at the SMARTS 1.5m telescope. It is fed by fiber and intended primarily for precise radial velocities.

  • Spectral resolution R~80000 (with image slicer: normal or Iodine mode) or R~25000 (fiber mode) or R~140000 (narrow-slit, bright stars), 3-pixel sampling
  • Spectral range 410-870 nm, fixed
  • Total efficiency ~6%
CHIRON is operational since 2011B. After recent upgrade, it is back in service since March 2012.
CHIRON replaces the previous spectrometer at 1.5m, FIBER ECHELLE
