Depth of fractured surface layer h (isolines), expressed as a fraction of meteoroid’s radius R, which prevents propagation of the damage deeper into the core in the plane of heliocentric distance d (abscissa) and size D of the body (ordinate). The core has the thermal and mechanical properties of a carbonaceous chondrite and the spin axis is perpendicular to the orbital plane (β = 90°, implying also θ₀ = 90°). Three values of the ratio ξ of the thermal conductivity in the surface layer K₁ to that in the core K₂ are tested: ξ = 1 (top panel), ξ = 0.5 (middle panel), and ξ = 0.1 (bottom panel).
