Scaled mass of the largest remnant (M_lr/M_tot) with respect to the impact energy scaled by the catastrophic disruption criterion (Q_R/$${\mathcal{Q}}_{\mathrm{R}\mathrm{D}}^{\ast }$$). The symbols and the colours are the same as in Fig. 1. The coloured lines correspond to the new scaling law in Eq. (5), with each colour representing a different value for the mass ratio (γ), as indicated by the squares on the colourbar. The black dashed lines represent the original LS12 universal law (Sect. 2.1.1). The most crowded regions are zoomed in the panels A (merging regime) and B (super-catastrophic regime).
