Shear viscosity of degenerate electron matter

Understand

We calculate the partial electron shear viscosity $\eta_{ee}$ limited by electron-electron collisions in a strongly degenerate electron gas taking into account the Landau damping of transverse plasmons.

• The Landau damping strongly suppresses $\eta_{ee}$ in the domain of ultrarelativistic degenerate electrons and modifies its %asymptotic temperature behavior.
• The efficiency of the electron shear viscosity in the cores of white dwarfs and envelopes of neutron stars is analyzed.
