The angular velocity of disruption ω_disr dependent on grain size for the ensembles of co-S (top panel), q-S (middle panel), and aC (bottom panel) grain materials dependent on the effective radius a_eff. Color coded are the BA (red), BAM1 (green), and BAM2 (blue) grains. Vertical bars are the range between minimal and maximal values of ωdisr resulting from our N-body disruption simulations while solid lines represent the best fit model.
