A nonstatic model of a radiating star is constructed with the energy-momentum tensor of a non-Pascal fluid and nonequilibrium radiation. The gravity equations are reduced to an equation which permits one to immediately generalize known analytic static solutions to nonstatic ones with radiation. The approximation of a homogeneous star is considered in detail, and an evaluation is performed which shows that for a Sun-like star physical parameters which follow from the model, lie between reasonable limits and agree with observations.
