What are hypervelocity planets and hypervelocity stars

[From: ] [author: ] [Date: 12-03-24] [Hit: ]
g. SDSS J090745.0+024507,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.......
science daily ne ws article is what i am refering to

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.
