High-velocity stars[edit]

I have a hunch that the frame of reference should be average motion of the stars in the neighbourhood of the star we consider, not "in the Sun's neighbourhood". It is completely non-intuitive to think about almost all stars of the bulge and from other sectors of the Milky Way as "high-velocity stars" due to such a heliocentric prejudice.

There is a mention that one of the known Hypervelocity stars is believed to be from the Large Magellanic Cloud. As per this study: It has been ruled out at the 3σ level. Just thought I'd mention it for you guys to consider... acoyauh (talk) 18:29, 3 October 2012 (CST)

HVS origin: White dwarf supernovae produce no neutron stars - huge mistake there[edit]

I strongly suggest consulting any classic text book for Astronomy 101 - and see that neutron stars result from core collapse supernovae. Other type of supernovae occur in white dwarfs as part of a binary system. These core detonation or white dwarf supernovae are a different type, not related with core collapse supernovae, where in fact neutron stars can be formed. This is not a matter of opinion, but one of the fundamental facts about supernovae. This is a blunt ugly error that should be corrected immediately.

I suggest a new article should be forked, focused specifically on "hyper-velocity stars"[edit]

I encounted this article when someone added a link to [[Stellar kinematics#High-velocity stars|hyper-velocity]].

In my opinion, if something is worthy of a wikilink it almost certainly deserves a standalone article.

IMO this article should say something like:

Hyper-velocity stars[edit]

Main article: Hyper-velocity stars
Hyper-velocity stars have acquired velocities greater than the escape velocity of our Galaxy. Events that speed up a star to hyper-velocity include: a close encounter with a super-massive black-hole; being a very close companion of a star that goes supernova.

Runaway star[edit]

We have found many runaway stars, specially recently some have been recognized by scientists. These galaxies are escaping their home into infinity void space forever. Read more here:
