Strongly coupled Coulomb and nuclear plasma in inner crusts of neutron stars

Abstract

Matter of subnuclear density in the inner crusts of neutron stars consists of neutron-rich atomic nuclei immersed in strongly degenerate relativistic gas of electrons and strongly nonideal liquid of neutrons. We give a brief account of thermodynamic and kinetic properties of this matter which are greatly affected by Coulomb and nuclear interactions (a companion paper on the outer envelopes is astro-ph/0012316) and show how they can be studied from observations of thermal radiation of young (age < 100 yr) neutron stars (for a discussion of the latter possibility, see astro-ph/0012306).
