Abstract

A special form of the Bondi news function can be associated with an infinite static cosmic string. In case of a radiating isolated system pierced by an infinite cosmic string, the total news function will be composed of two parts - one characterizing the radiation field, the other the string. Some examples are discussed and related to a recently given solution, which was interpreted as an outgoing gravitational wave due to the splitting of an infinite cosmic string.
