1 Oct 1998 | Journal: | Mon.Not.Roy.Astron.Soc. 310 (1999) 557 | Subject: | gr-qc | Affiliation: | Natal), Roy Maartens (Portsmouth), Sunil Maharaj (Natal | Abstract: | 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. | Source: | arXiv, gr-qc/9810001 | Services: | Forum | Review | PDF | Favorites |
