Fig. 7. 3D diagram of the trajectories of nebular gas composition in ¹⁰Be/⁹Be, Δ⁵¹V (‰), and time (years) space, in the case of irradiation at 0.02, 0.1, 0.5, and 1.0 AU by gradual and impulsive flares.

(A) Expected ¹⁰Be/⁹Be variations associated with ∆⁵¹V values of ~−0.2‰ (black dots). (B) Expected δ⁵¹V variations associated with a canonical ¹⁰Be/⁹Be of ~8 × 10⁻⁴ (black dots). 2D projections of (A) and (B) are provided in the Supplementary Materials to facilitate readability.
