Abstract: On Detecting gravitational waves with the Moon
Abstract: It has been suggested to measure the eigenmodes of the Moon excited by gravitational waves. Such a resonant bar detector could become a valuable partner observatory for gravitational waves working alongside LISA and other future detectors. We discuss in this talk the excitation of resonant eigenmodes by gravitational waves within Einstein and Brans-Dicke gravity. In the latter case, gravitational waves obtain an additional polarisation. In spherical detectors, it is possible to extract information on the polarisation of the gravitational wave. Such detectors are therefore a way to search for theories of gravity beyond general relativity. I will discuss the calculations of the displacement by gravitational wave resonant with the eigenmodes of the Earth and Moon, and comment on the frequency range for the potential Lunar gravitational wave antenna.
