Stable, unstable, and breakup regions in the (ρ_b − Ω) parameter space. With reference to the numerical simulations performed in this work, green and red regions denote initial conditions forming nondis-rupted and disrupted aggregates, respectively. The breakup transition is marked by the solid red line, and the theoretical limit for equilibrium reported in Eq. (3) is represented by the dashed red line. The intermediate region between the theoretical equilibrium and the breakup lines (light green area) includes aggregates that are not in equilibrium, but that are able to reshape without breaking apart. The vertical dashed blackline reports the maximum ρ_b value used in simulations. For reference, we report current (ρ_b − Ω) estimates (and their uncertainty) for asteroids Didymos (Naidu et al. 2020) and Moshup (Ostro et al. 2006).
