Gravitational radiation from kinky infinite strings

Posted by in category: futurism

Year 1990 😗


The radiation from small amplitude waves on straight strings is calculated. The result is applied to a string with colliding kinks, and the power spectrum and total power obtained. The rate of rounding of the kinks due to gravitational damping is found, which enables one to show that the backreaction causes the average separation between kinks on infinite strings to scale with the horizon in an expanding universe.
