Distribution of runaway stars in the V_Sp − v sin i plane. Stars with orbits remaining within the Galactic disk are marked as black dots, those with disk-passing orbits as red stars, and possible cluster-origin runaways as cyan squares. Thresholds of v sin i = 61 km s⁻¹ and V_Sp = 126 km s⁻¹ (dashed lines) represent the 3σ values obtained from Maxwellian fits to the observed distributions, as described in Sect. 4.3 of Guo et al. (2024).
