Figure 39: Mass of the crust shell for the ground-state crust and for the accreted crust. The total stellar mass is M = 1.4M ⊙. Accreted crust: EoS of Haensel & Zdunik [185]. Ground-state crust: same compressible liquid drop model of atomic nuclei of Mackie & Baym [277], but full thermodynamic equilibrium (cold catalyzed matter). The black dots indicate the neutron drip transition. Left panel: fractional mass of the crust shell, ΔM ∕M, vs. its bottom density ρ. Right panel: ΔM ∕M versus depth below the star surface, z.
