a−e diagram from the last Gyr of the benchmark model simulation incorporating gravitational interaction with Neptune. The enhanced gravity effect is accounted for in the model using the interpolating function . yields Q₂ = 5.9. Only the evolution of test particles in orbits with inclinations spanning i ∈ (10,30) deg, which is the interval that the inclinations of Sednoids lie in, is shown. Sedna and 2012 VP 113 are indicated as large dots. The dashed lines indicate q = 30, 50, 100, and 550 au levels (from right/bottom to left/upwards).
