Something very similar happens in a laser cooling apparatus, except such devices start with a warm cloud of atoms moving in numerous directions at variable velocity.

Suspected variable radial velocity.

In 1899, American astronomer W. W. Campbell announced that Zeta Geminorum has a variable radial velocity.

HD 221148 is variable star, variable radial velocity.

Based on the variable radial velocity of this star, in 1967 it was suggested that the primary is a double-lined spectroscopic binary.

HD 43587 did not seem to have a variable radial velocity or much variability in its astrometry which would indicate that it had a close companion.

He claims to have proven that the device practically works like a catapult while a variable angular velocity can only control the smoothness of the object velocity to which the drive is attached.

In 1900, William W. Campbell and William H. Wright used the Mills spectrograph at the Lick Observatory to determine that this star has a variable radial velocity.

There was an almost constant rainfall, and an inshore wind of variable velocities up to full gale force.
