Final distribution on the Galactic plane of solar siblings when M_c = 804.6 M_⊙ and R_c = 3 pc. The final phase-space coordinates of the solar siblings depend on the configuration of the Galactic potential. Top: the Sun’s siblings are dispersed on the Galactic disk. Bottom: the solar siblings are located in a specific region on the Galactic disk. The dashed black lines represent the potential of the spiral arms at the end of the simulation.
