Generation and Propagation of Sound Waves in a Collapsing or Anti-Collapsing Star with Uniform Density

摘要

In our Research Note (dated on December 10th, 1965), we have dealt with the generation and propagation of sound waves in a collapsing or anti-collapsing star with uniform density. It seems that its contents do not lose their physical meaning even at the present time. This is the reason why we reproduce the Research Note. (ERA citation 13:023272)
