Query: Relaxational effects in radiating stellar collapse   Relaxational effects in stellar heat transport can in many cases be
significant. Relativistic Fourier-Eckart theory is inherently quasi-stationary,
and cannot incorporate these effects. The effects are naturally accounted for
in causal relativistic thermodynamics, which provides an improved approximation
to kinetic theory. Recent results, based on perturbations of a static star,
show that relaxation effects can produce a significant increase in the central
temperature and temperature gradient for a given luminosity. We use a simple
stellar model that allows for non-perturbative deviations from staticity, and
confirms qualitatively the predictions of the perturbative models.
