SummaryA star of mass M and radiusr0 is supposed to start radiating at timet0. The zone of radiation extends tor=r1 at a later instantt=t1. The energy tensor for the radiation zone, describing the directed flow of radiation, is evaluated and a relativistic line-element representing the field of radiation forr0 ⩽r ⩽r1 and correspondingt0 ⩽t ⩽t1 is obtained. It is shown that certain quantitiesm,v1,r2ρ, etc., are conserved in the field along a world-line of flow. Atr=r0,t=t0 and atr=r1,t=t1, the… Expand
