Durability of Neutron Star Crust
How long do neutron star mountains last? The durability of elastically deformed crust is important for neutron star physics including pulsar glitches, emission of gravitational waves from static mountains, and flares from star quakes. The durability is defined by the strength properties of the Yukawa crystals of ions, which make up the crust. In this paper we extend our previous results [Mon. N...
متن کاملEffect of BCS pairing on entrainment in neutron superfluid current in neutron star crust
The relative current density n of “conduction” neutrons in a neutron star crust beyond the neutron drip threshold can be expected to be related to the corresponding particle momentum covector pi by a linear relation of the form n i = Kpj in terms of a physically well defined mobility tensor K ij . This result is describable as an “entrainment” whose effect – wherever the crust lattice is isotro...
متن کاملShear modulus of neutron star crust
The shear modulus of solid neutron star crust is calculated by the thermodynamic perturbation theory, taking into account ion motion. At a given density, the crust is modelled as a bodycentred cubic Coulomb crystal of fully ionized atomic nuclei of one type with a uniform charge-compensating electron background. Classic and quantum regimes of ion motion are considered. The calculations in the c...
متن کاملBreaking stress of neutron star crust
The breaking stress (the maximum of the stress–strain curve) of neutron star crust is important for neutron star physics including pulsar glitches, emission of gravitational waves from static mountains and flares from star quakes. We perform many molecular dynamic simulations of the breaking stress at different coupling parameters (inverse temperatures) and strain rates. We describe our results...
متن کاملCoulomb crystals in neutron star crust
It is well known that neutron star crust in a wide range of mass densities and temperatures is in a crystal state. At a given density, the crystal is made of fully ionized atomic nuclei of a single species immersed in a nearly incompressible (i.e., constant and uniform) charge compensating background of electrons. This model is known as the Coulomb crystal model. In this talk we analyze thermod...
