Tibsfox/gsd-skill-creator ↗What it does
Classify stars and measure radial velocity from spectra
Best for
Inferring chemical composition and physical state of distant stars from their light.
Inputs
- · stellar spectrum (flux vs wavelength)
- · reference comparison spectra
Outputs
- · OBAFGKM spectral type
- · luminosity class (I-VII)
- · temperature
- · radial velocity
- · chemical abundances
Preconditions
Spectrum obtained with spectrograph; continuum and line identification required
Failure modes
- · Interstellar extinction not corrected
- · Rotationally broadened lines hide classification
- · Binary star lines blended
Trust signals
- · OBAFGKM sequence linked to ionization physics
- · Payne-Gaposchkin 1925 H-abundance example
- · curve-of-growth analysis protocol
