The Differential Doppler effect occurs when light is emitted from a rotating source.
In
circumstellar environments it describes the difference in photons arriving at orbiting dust particles. Photons that originate from the limb that is rotating away from the particle are
red-shifted, while photons emitted from the limb rotating toward the particle are
blue-shifted.

Doppler effect
The Doppler effect (also Doppler shift) is the change in the frequency of a wave in relation to an observer who is moving relative to the source of the wave. The ''Doppler effect'' is named after the physicist Christian Doppler, who described ...
