Erosion thresholds for a loosely bound pebble-pile planetesimal with radius, RP, in dependence of the eccentricity, e, and semimajor axis, a. The planetesimals consist of millimetre-sized pebbles and the cohesion between the pebbles is described with the effective surface energy, γeff = 10−4 N m−1 taken from experiments (Demirci et al. 2020).
