NGC 1851A: Revealing an ongoing three-body encounter in a dense globular cluster

Open Access

Fig. 7.

Allowed solutions showing the mass m₃, asymptotic velocity v_∞, and relative distance R for a nearby star in a fly-by encounter, in the core of the globular cluster. Constant ${\dot{ω}}_{tidal} / {\dot{ω}}_{obs}$ $\dot\omega_{\mathrm{tidal}}/\dot\omega_{\mathrm{obs}}$ and constant ẋ_tidal are shown with black dotted and crimson dash-dotted lines respectively in the bottom plot.
