A hypervelocity star is one going abnormally fast, with enough speed to escape its parent galaxy gravitational speed. E.g. SDSS J090745.0+024507, "leaving the Galaxy with a heliocentric radial velocity of 853 ± 12 km s-1"
A hypervelocity planet is a planet in orbit around such a star. A couple of astrophysicists have done a simulation to show that it would be possible for a planet to survive the acceleration of its parent star, so they think we should look for them.
