Hypervelocity Stars
Hypervelocity Stars
Hypervelocity stars are the fastest stars in the Universe. These objects have such high velocities that they exceed the escape speed from the host Galaxy!
The leading mechanism for explaining such extreme velocities is the disruption of a binary system following its interaction with the massive black hole located in the centre of our Galaxy. These stars have been proposed as powerful tools for studying both the stellar population in the Galactic Centre, and to derive important information on the matter content of the Milky Way. Since they travel through the Galactic potential, their trajectories can be used to trace and constrain the matter and dark matter distribution.

The Fastest Stars in Gaia EDR3:
The catalogue containing the full 6D phase space distribution in Galactocentric coordinates for the ~7 million stars in Gaia EDR3 with precise parallaxes and with a radial velocity measurement from Gaia DR2 can be downloaded HERE (2.9 GB fits file).
The catalogue providing distances and velocities for the same subset of stars, but subtracting the parallax zeropoint to the quoted Gaia EDR3 parallax, can be downloaded HERE (3GB fits file).
A full description of the content of the catalogues can be found in Appendix B, Table B1, of this paper.
