Question

In a non-degenerate plasma, why are e-e collision negligible compared to e-ion for thermal conduction?

Answer 1

$\mathfrak{\blue{\huge{answer \: :-}}}$

1) why conduction is said to be negligible (for non-degenerate matter)

and

2) when convection happens and is dominant.

Answer 2

Electrical and thermal conductivities of dense plasmas under conditions which take place in the stars have been studied by large number of authors over the twentieth century. Milestones on the theoretical investigation are the classical works .Their co-workers, as well as other theoretical groups. It would be impossible to give the appropriate credit to all of them in this short introductory note. We restrict ourselves to a brief account only of the results obtained at the Department of Theoretical Astrophysics (DTA) of the Ioffe Institute since late 70s, which are implemented in the Fortran codes .
