Requested move[edit]

The result of the move request was page moved. Anthony Appleyard (talk) 20:38, 5 November 2009 (UTC)[reply]

J0806 → RX J0806.3+1527 — This is the name used in scientific references, and research material, and the one that can specifically identify the object, since "J0806" is just half of a coordinate set, meaning little (like 45 degrees North - what does that mean? Not much - you can't identify a spot on the Earth with half a coordinate.) 70.29.209.91 (talk) 04:40, 29 October 2009 (UTC)[reply]

Discussion[edit]

"J0806" cannot be used to identify this object in SIMBAD, the standard astronomical reference search engine for objects within the galaxy [1] ; SIMBAD and the more scholarly references and external links use "RX J0806.3+1527" [2]

I don't see how this could have failed a speedy rename... 70.29.209.91 (talk) 04:45, 29 October 2009 (UTC)[reply]

Survey[edit]

Support – Suggested rename is a proper astronomical designation for this star, whereas J0806 is not.—RJH (talk) 23:42, 3 November 2009 (UTC)[reply]

Distance estimate[edit]

There appears to be a factor of 10 discrepancy in the estimated distance to the system. The cited source from the Chandra release gives a range of "about 1,600 light years" and is dated 2005. A more recent paper estimates 5kpc in the formal paper preprint and approximately 16,000 light years in the press release. The latter is from 2010 so presumably more accurate. Can anyone confirm the latest figure? George Dishman (talk) 12:32, 16 September 2015 (UTC)[reply]

Typo in Chandra release? Ruslik_Zero 20:17, 16 September 2015 (UTC)[reply]

I've seen the same thing, many of the sources I've read (including several research papers listed here in "Further Reading", e.g. section 4.3 of this one) cite 16,000 light years or 5 kiloparsecs as the distance. --71.204.62.62 (talk) 17:33, 16 April 2017 (UTC)[reply]
