Scientific paper

In this paper we present a new class of nonsingular solutions representing time dependent balls of perfect fluid with matter-radiation in general relativity. The solution of the class is suitable for interior modeling of a quasar i.e. a massive radiating star. The interior solution is matched with a zero pressure Vaidya metric. From this solution we constructed a quasar model by assuming the life time of the quasar of ≈107 year. We obtained a mass of the quasar of ≈109 M θ , linear dimension ≈1017 km and a rate of emission L ∞≈1047 erg/s.
