Breakup distance as a function of the clump mass. The clump is a rocky (MgSO₃) object with a density of ρ_cl = 5 g cm⁻³ and an internal friction angle of ϕ = 45°. The dotted, dashed, and dash-dotted line corresponds to the cohesive strength of C= 0.1, 1, and 10 MPa, respectively. The solid line represents an iron clump with ρ_cl = 8 g cm⁻³, C = 50 MPa, and ϕ = 37°. The horizontal lines represent the light cylinder radii for NSs with different spin periods.
