Figure 3. Primary-Centric Framework synchrony diagram. The blue curve shows the orbital angular velocity Ωorb(a) while the dashed line represents the primary spin angular velocity Ωprimary. The intersection defines the tangible synchrony radius aG1 for the S4716–Sagittarius A* system [Credit: Author]
