Statistics of survived test Trojans for different initial resonant angles σ0 within the control model of Jupiter migration (i.e. amplitude ΔaJ = 0.5 AU and e-folding time τ = 1000 yr).
∆σ0 | N4 | A4 | N5 | A5 | R45 |
---|---|---|---|---|---|
0–80 | 399 | 1–51 | 350 | 1–51 | 1.14 |
10–80 | 394 | 2–51 | 309 | 3–50 | 1.27 |
20–80 | 356 | 8–52 | 277 | 11–52 | 1.29 |
30–80 | 312 | 15–54 | 209 | 18–56 | 1.50 |
30–70 | 356 | 10–46 | 256 | 10–52 | 1.39 |
Notes. For each ∆σ0, there are 500 L4 samples with σ0 in the range of 60° + ∆σ0 and 500 L5 samples with symmetric σ0 in the range of −60° − ∆σ0. After the 1 Myr evolution, we derive the numbers (N4, N5) and the final resonant amplitudes (A4, A5) of survived Trojans, with subscripts ‘4’ and ‘5’ for the L4 and L5 swarms respectively. The number ratio R45 = N4/N5 is presented in the last column.
