Scientific paper

The dynamical instability of a spherically symmetric fluid which collapses nonadiabatically undergoing dissipation in the form of a radial heat flow is studied. The Newtonian and post-Newtonian limits are considered and the range for dynamical instability for the ratio of specific heats gamma is given. The Newtonian correction due to dissipation increases the instability of the fluid while the relativistic correction due to dissipation makes the fluid less unstable.
