Abstract
Exact gravitational solutions with radial pressure and heat flow are obtained by integrating the field equations. Junction conditions which match the collapse solutions to the exterior Vaidya metric show that, at the boundary, the pressure is proportional to the magnitude of the heat flow vector. This condition allows us to determine the time-dependent functions of the interior solutions.
