Abstract
AbstractWe present a hydrodynamic model that describes excitation of linear stellar oscillations by a stochastic background of gravitational waves (SBGW) of astro‐physical and cosmological origin. We find that this excitation mechanism is capable of generating solar g‐mode amplitudes close to or comparable with values expected from excitation by turbulent convection, which is considered to be the main driving force for solar‐like oscillations. A method is presented that places direct upper bounds on the SBGW in a frequency range, in which the SBGW is expected to contain rich astro‐physical information. Employing estimates for solar g‐mode amplitudes, the proposed method is demonstrated to have the potential to compete with sensitivities reached by gravitational wave experiments in other frequency ranges (© 2012 WILEY‐VCH Verlag GmbH & Co.
