Star plus compact-object binary encounters in globular clusters likely ejected about 6,300 Milky Way stars in the last 500 Myr, including roughly 840 stars faster than 500 km/s, almost none of which are detectable in Gaia DR3.
A sample of 69 stars with thin-disk-like abundances but slow or retrograde orbits is identified, with dynamical ejection from globular clusters emerging as the most common plausible origin.
A warm carbon-oxygen white dwarf with intermediate-mass element enhancement and a ~2000 km/s space velocity is identified as the surviving donor of a D6 double-detonation supernova.
About nine of the sixteen classifiable hypervelocity stars appear to have been ejected by a roughly 600,000-solar-mass black hole in the Large Magellanic Cloud, which also explains their clustering in Leo.
Interstellar objects may contribute enough baryonic mass to reduce the local dark matter halo density to 0.24 GeV/cm³.
