The equilibrium properties of the outer crust of cold nonaccreting magnetars (i.e. neutron stars endowed with very strong magnetic fields) are studied using the latest experimental atomic mass data complemented with a microscopic atomic mass model based on the Hartree-Fock-Bogoliubov method. The Landau quantization of electron motion caused by the strong magnetic field is found to have a significant impact on the composition and the equation of state of crustal matter. It is also shown that the outer crust of magnetars could be much more massive than that of ordinary neutron stars.

The recombination currents in the space charge layer of abrupt pn junctions, calculated by computer, for different doping levels and different position of recombination levels in the semiconductor energy gap, are presented. The movement of the point of maximal recombination rate is shown when the forward bias voltage applied to p‐n junction is changed. Approximate expressions and method for calculation are given which may be used for calculation of the recombination current in these p‐n junctions with an error smaller than 12%.

Abstract.We have recently developed a set of equations of state based on the nuclear energy density functional theory providing a unified description of the different regions constituting the interior of neutron stars and magnetars. The nuclear functionals, which were constructed from generalized Skyrme effective nucleon-nucleon interactions, yield not only an excellent fit to essentially all experimental atomic mass data but were also constrained to reproduce the neutron-matter equation of state as obtained from realistic many-body calculations.
