Theoretical calculations are carried out of solar oscillations caused by gravitational waves from a binary system such as the gamma ray emitter Geminga. The waves would raise tides in the sun as they passed through it. The analytical model describes fluctuations in the curvature tensor, due to the gravitational waves. The waves are treated in terms of a time delayed reduced quadrupole mass-moment tensor emitted from the center of mass of the binary system. Account is taken of the complex spherical harmonics in the waves. An equation is obtained for the forced adiabatic solar oscillation and its amplitude, and to dissipation of the pulsational energy in the sun. It is shown that the peak amplitude of the projected oscillation will be at least a thousand times smaller than that of the solar 160 min oscillations, so Geminga cannot be causing the oscillations.
