TY - JOUR AU - Zimdahl, Winfried PY - 2022/02/01 Y2 - 2024/03/30 TI - On the mode structure of imperfect fluids JF - Cadernos de Astronomia JA - Cad. Astro. VL - 3 IS - 1 SE - Artigos DO - 10.47456/Cad.Astro.v3n1.36856 UR - https://periodicos.ufes.br/astronomia/article/view/36856 SP - 101 AB - <p>This paper tries to present a simple picture of several aspects of the mode structure in relativistic non-equilibrium thermodynamics. Its pedagogical focus is on the relation between long-wavelength perturbation modes of the causal Müller-Israel-Stewart (MIS) theory and those of the traditional Eckart theory. Principally, this issue was clarified in a series of papers by Hiscock and Lindblom. Here, I put together some essential features of this topic which do not require the entire formalism of the complete theory.</p> ER -
