Relativistic models of thin disks immersed in a Robertson-Walker type spacetime

Year: 2013

Type: article

Abstract: Using the well known "displace, cut and reflect" method used to generate disks from given solutions of Einstein field equations, we construct somerelativistic models of time dependent thin disks of infinite extension made of a perfect fluid based on the Robertson-Walker metric. Two simple families of models of disks based on Robertson-Walker solutions admitting Matter and Ricci collineations are presented. We obtain disks that are inagreement with all the energy conditions.
