Scale Symmetries of Spherical String Fluids

arXiv:gr-qc/9906080 · doi:10.1063/1.532942

Abstract

We consider homothetic maps in a family of spherical relativistic star models. A generalization of Vaidya's radiating metric provides a fluid atmosphere of radiation and strings. The similarity structure of the string fluid is investigated.
