Kinematic resonance and the memory effect in free mass gravitational antennas
Abstract
Consideration is given to two effects in the motion of free masses subjected to gravitational waves, kinematic resonance and the memory effect. In kinematic resonance, a systematic variation in the distance between the free masses occurs, provided the masses are free in a suitable phase of the gravitational wave. In the memory effect, the distance between a pair of bodies is different from the initial distance in the presence of a gravitational radiation pulse. Some possible applications of kinematic resonance and memory effect in experimental programs are discussed, with attention given to a program to detect gravitational radiation from binary stars; and the high-precision optical interferometry satellite (POINTS) program. It is shown that allowance for kinematic resonance and the memory effect in gravitational wave observations should lessen the demands on recording systems and enhance the sensitivity of gravitational antennas.
