摘要：
The gravitational instability of a fully ionized gas is analyzed within the framework of linear irreversible thermodynamics. In particular, the presence of a heat flux corresponding to generalized thermodynamic forces is shown to affect the properties of the dispersion relation governing the stability of this kind of system. The overall weight of the sole Dufour effect on the value of Jeans wavenumber is shown to be negligible.
