Query: Could the pulsars actually be oscillators?   A simplified form of a nonsymmetric metric is used to develop the coupling of
the electrostatic and gravitational fields, which only occurs in dynamic
solutions. The coupling results in a resonance in an object near the
Schwarzschild radius. The resonator is unique in that the frequency decreases
with radius, reaching a lower limit near 0.4 Hz at the gravitational limit. The
limiting frequency does not depend on the mass or any other parameter. It is a
constant of physics. Gravitational contraction supplies energy to the
resonator, causing it to break into oscillation. The solution is in reasonable
agreement with the properties of the mainstream pulsars. An observational test
to determine if the pulsars are oscillators has never been performed, and an
observational technique is developed for distinguishing between the rotational
and oscillatory cases.
