Illustrative Spectra

Below are examples of high signal-to-noise spectra for a variety of stellar types, highlighting major spectral features. The stellar parameters indicated for each star:

  • effective temperature (Teff),
  • surface gravity (log g)
  • metallicity [Fe/H]
are derived from the observational data via the SEGUE Spectral Parameter Pipeline (SSPP).

  • A Stars
  • Blue Horizontal Branch Stars
  • Carbon-Enhanced Metal-Poor Stars
  • F Turnoff Stars
  • G Dwarfs
  • K Dwarfs
  • K Giants
  • Low Metallicity Stars
  • White Dwarfs
