摘要
We study the scattering of a scalar field, massive or massless, by a collapsing spherical star. The main point of interest is the infinite Doppler effect measured by an observer, al rest in Schwarzschild coordinates. We construct the functional framework associated with this phenomenon, and we prove the existence and strong asymptotic completeness of the wave operators describing the scattering of the field by the space-time curvature and the asymptotically characteristic moving boundary of the star.
