Gaia-derived parameters for 13 Orion clusters fed into N-body simulations reveal two regimes: seven with α_vir ≲ 7 retain bound cores for ≳170 Myr while six with α_vir ≳ 7 dissolve before 120 Myr.

Core-scale magnetic fields in star-forming regions are more disordered than cloud-scale fields and align randomly with core orientations and velocity gradients.
The CH₃OH/CH₃CN ratio in the S68N outflow is constant at ~100-200 and matches gas-phase astrochemical models only when cosmic-ray ionization rates are raised to ~10^{-14} s^{-1}.
