A Rotating frame of reference is not an inertial frame of reference because a rotation is an acceleration, by definition.

Possible applications

Some Gamma ray burster observations are detecting x-ray and gamma ray jets which may be due to rapidly rotating neutron stars. It is not yet understood how these potentially large bodies could be rotating rapidly enough to emit x-rays; thus the physical processes involved require further characterization.
