abstract

Elastic properties of the solid regions of neutron star crusts and white dwarfs play an important role in theories of stellar oscillations. Matter in compact stars is presumably polycrystalline and, since the elastic properties of single crystals of such matter are very anisotropic, it is necessary to relate elastic properties of the polycrystal to those of a single crystal. We calculate the effective shear modulus of polycrystalline matter with randomly oriented crystallites using a self-consistent theory that has been very successful in applications to terrestrial materials and show that previous calculations overestimate the shear modulus by approximately 28%.

Plasticity of Neutron Star Crusts

astro-ph.HE · 2026-06-04 · unverdicted · novelty 7.0

MD simulations identify a universal post-break plastic flow in neutron star crusts at shear strains of 0.05-0.11, independent of initial crystal structure.

Crust glass formation reveals the neutron star birth properties in IGR J17480-2446

astro-ph.HE · 2026-06-20 · unverdicted · novelty 6.0

Accretion-induced failure of the neutron star crystal crust produces a glass layer that explains the observed cooling, fixes the accreted mass at 2.4e-6 solar masses, and indicates birth properties typical of recycled neutron stars, potentially from electron-capture supernova formation.
