【 摘 要 】

The evolutionary dynamics of normal modes, non-adiabatic magneto-hydro-dynamic (MHD) waves, in the prominence plasmas in the presence of kinematic viscosity and inertia-dependent species stratification is herein explored. It judiciously implements a new energy equation devised to describe optically thin radiation losses, thermal conduction, viscosity, heating mechanisms, and so forth. The dispersion analysis demonstrates that the thermal conduction plays as a primary sink for both the wave classes of fast and slow spectral groups. Finally, asynoptic indication to further refinements and scopes is concisely stressed.
