I changed the currently known HVSs to nine after reading an article in this weeks newscientist (22nd July 2006), although i can't find any info on the internet regarding the other 4 stars. I don't think that newscientist would report the wrong number but i can't be sure, so i though i would leave a note to anyone who may know more that i. --D4n08:23, 26 July 2006 (UTC)
The following is a closed discussion of the proposal. Please do not modify it. Subsequent comments should be made in a new section on the talk page. No further edits should be made to this section.
The result of the proposal was No merge
Don't merge - It seems that hypervelocity refers to stars that interact with a massive black hole at the center of a galaxy [1] while runaway is thought to be caused by a supernova in a close binary system [2]. The two concepts are similar in that they both involve high velocity, but the cause is distinct and the articles should not be merged.--mikeu22:26, 4 June 2007 (UTC)
Do not merge - The information from www.daviddarling.info does not appear to be quite accurate, but the articles still should not be merged. High velocity stars are indeed thought to be stars ejected from the center of the Milky Way by interactions with the central black hole, but the term "runaway star" appears to be used for stars ejected from dense clusters (see [3], for example) or stars ejected from binary star systems when their companions become supernovae (see [4], for example). The two are apparently separate topics and should be described separately. Dr. Submillimeter14:13, 21 July 2007 (UTC)
No, do not merge. Runaway stars are a generic name for stars that are not in an identifiable orbital relationship with other bodies. Hipervelocity stars, although falling in this category, are defined as having a speed at or above escape velocity, which means they travel fast enough to defeat the gravitational pull of the galaxy. Very few Runaway stars show this velocity, so the distinction is necessary. (Acoyauh, 29 november 2007)
