Moment of inertia of accreted NSs. Top panels: total moment of inertia I (left panel) and fractional moment of inertia of the crust I_crust/I (right panel) in cgs units as a function of the NS mass. Results with accreted or catalyzed crust are indistiguishable. Bottom panel: difference ΔI_crust of the crustal moment of inertia between accreted and catalyzed NSs. Calculations were performed for the EoS based on the BSk21 EDF.
