Comparison of the ejection velocity distributions of ISOs produced during the post-main sequence phase (unpublished material based on Veras et al. 2014b, orange), the flyby scenario computed here (dark blue) and during the planet scattering phase (adapted from Adams & Spergel 2005, light blue). The last is only partly shown, it extends further to the higher values. The velocity bin width is 0.05 km s⁻¹ for the flyby and post-main sequence scenario and 1 km s⁻¹ for the planet scattering case.
