Abstract
In this work the Dirac equation for massless left-handed neutrinos has been set up for the Vaidya background which describes the exterior of a spherically symmetric radiating source. With a particular Ansatz fo r the form of both the spinor and the background metric, analytical so lutions of the Dirac equation are obtained. The coordinates in which t he particular Vaidya metric assumes diagonal form are also found.
