Abstract
We study a coupled system of gravitational waves and a domain wall whi ch is the boundary of a vacuum bubble in de Sitter spacetime. To treat the system, we use the metric junction formalism of Israel. We show t hat the dynamical degree of the bubble wall is lost and the bubble wal l can oscillate only while the gravitational waves go across it. This means that the gravitational back reaction on the motion of the bubble wall cannot be ignored.
