A Survey of Chemical Separation in Accreting Neutron Stars
Ryan Mckinven, Andrew Cumming, Zach Medin +1
The heavy element ashes of rp-process hydrogen and helium burning in accreting neutron stars are compressed to high density where they freeze, forming the outer crust of the star.…
Time-dependent, compositionally driven convection in the oceans of accreting neutron stars
Zach Medin, Andrew Cumming
We discuss the effect of chemical separation as matter freezes at the base of the ocean of an accreting neutron star, and the subsequent enrichment of the ocean in light elements a…
A signature of chemical separation in the cooling curves of transiently accreting neutron stars
Zach Medin, Andrew Cumming
We show that convection driven by chemical separation can significantly affect the cooling curves of accreting neutron stars after they go into quiescence. We calculate the thermal…
Direct MD simulation of liquid-solid phase equilibria for three-component plasma
J. Hughto, C. J. Horowitz, A. S. Schneider +3
The neutron rich isotope 22Ne may be a significant impurity in carbon and oxygen white dwarfs and could impact how the stars freeze. We perform molecular dynamics simulations to de…
Compositionally-driven convection in the oceans of accreting neutron stars
Zach Medin, Andrew Cumming
We discuss the effect of chemical separation as matter freezes at the base of the ocean of an accreting neutron star, and argue that the retention of light elements in the liquid a…
Crystallization of classical multi-component plasmas
Zach Medin, Andrew Cumming
We develop a method for calculating the equilibrium properties of the liquid-solid phase transition in a classical, ideal, multi-component plasma. Our method is a semi-analytic cal…
