Abstract
We present a conformally-flat metric in general relativity representing the gravitational field of a spherically-symmetric material distribution-radiating energy in the form of photons and neutrinos. A particular case of the solution is discussed and the corresponding expressions for mass function, linear dimension, and the luminosity have been derived. The solution seems to be physically sound as it corresponds to positive expressions for fluid pressure, fluid density, and radiation flux density.
