Abstract
We search exact analytical solutions of spherically symmetric dissipative fluid distributions satisfying the vanishing expansion condition (vanishing expansion scalar ). To do so we shall impose additional restrictions allowing the integration of the field equations. A detailed analysis of the obtained solutions, their prospective applications to astrophysical scenarios, as well as alternative approaches to obtain new solutions, are discussed.
