Phase separation in the crust of accreting neutron stars.
نویسندگان
چکیده
Nucleosynthesis, on the surface of accreting neutron stars, produces a range of chemical elements. We perform molecular dynamics simulations of crystallization to see how this complex composition forms new neutron star crust. We find chemical separation, with the liquid ocean phase greatly enriched in low atomic number elements compared to the solid crust. This phase separation should change many crust properties such as the thermal conductivity and shear modulus.

The properties of the outer crust of non-accreting cold neutron stars are studied by using modern nuclear data and theoretical mass tables updating in particular the classic work of Baym, Pethick and Sutherland. Experimental data from the atomic mass table from Audi, Wapstra, and Thibault of 2003 is used and a thorough comparison of many modern theoretical nuclear models, relativistic and non-r...
متن کاملPycnonuclear burning of 34Ne in accreting neutron stars
We study the pycnonuclear burning of 34Ne in the inner crust of an accreting neutron star. We show that the associated energy production rate can be calculated analytically for any arbitrary temporal variability of the mass accretion rate. We argue that the theoretical time-scale for 34Ne burning is currently very uncertain and ranges from a fraction of a millisecond to a few years. The fastest...
متن کاملThe Ocean and Crust of a Rapidly Accreting Neutron Star: Implications for Magnetic Field Evolution and Thermonuclear Flashes
We investigate the atmospheres, oceans, and crusts of neutron stars accreting at rates sufficiently high (typically in excess of the local Eddington limit) to stabilize the burning of accreted hydrogen and helium. For hydrogen-rich accretion at global rates in excess of 10M⊙ yr −1 (typical of a few neutron stars), we discuss the thermal state of the deep ocean and crust and their coupling to th...
متن کاملThe rp Process Ashes from Stable Nuclear Burning on an Accreting Neutron Star
The temperature and nuclear composition of the crust and ocean of an accreting neutron star depend on the mix of material (the ashes) that is produced at lower densities by fusion of the accreting hydrogen and helium. The hydrogen/helium burning is thermally stable at high accretion rates, a situation encountered in weakly magnetic (B ≪ 10 G) neutron stars accreting at rates Ṁ > 10M⊙ yr −1 and ...
متن کاملMolecular Dynamics Simulations of Accreting Neutron Star Crust
Material accreting on a neutron star can undergo rapid proton capture nucleosynthesis to produce a variety of nuclei up to mass numbers around 100. This complex rp ash then undergoes electron capture as it is buried to higher densities. We perform molecular dynamics simulations to determine how this material freezes to form new neutron star crust. In addition, from our simulations we calculate ...
