| doppler broadeningnoun | (physics) The broadening of the spectral lines of a high-temperature or rapidly-rotating object due to redshifting of spectral lines from atoms and molecules moving away from the observer and blueshifting of spectral lines from atoms and molecules moving toward the observer. |
