'''Review''' – The article is in decent shape, although perhaps a little short. Here are a few observations:
* <s>The 'absolute magnitude' values in the infobox need a proper citation; just computing them isn't enough. (Kervella et al. (2008) give the absolute bolometric magnitudes for the two stars; it might be better to use that field instead.)</s>
:*Done. A better cite of stellar-database is now used. -[[User:The Herald|The Herald]] [[User talk:The Herald|<sup style="margin-left:0.5px">''the joy of the LORD''</sup>]][[Special:Contributions/The Herald|<sub style="margin-left:-47.5px">''my strength''</sub>]] 04:34, 19 March 2015 (UTC)
:** Ah, well you've replaced what was a perfectly suitable citation for the ''apparent'' magnitude with a different citation. The ''absolute'' magnitude values are not cited. :-) I would again suggest just using the Kervalla et al. (2008) citation and the absolute bolometric magnitude field of the template.

:::::I read [http://arxiv.org/pdf/1307.7038v1 it] but it seems to me like there aren't any IR excess as they say much about GJ 581, GJ 667C, and GJ 876 M-dwarfs. GJ 820 has its name only in the table. So should I include in the article that there aren't any IR excess? Plus, I couldn't deduce from them that there are any habitable zones either. -[[User:The Herald|The Herald]] [[User talk:The Herald|<sup style="margin-left:0.5px">''the joy of the LORD''</sup>]][[Special:Contributions/The Herald|<sub style="margin-left:-47.5px">''my strength''</sub>]] 04:27, 21 March 2015 (UTC)
:::::: Yes, the absence of a detectable IR excess is still of interest because it tells the reader something about the state of the system. The reference for the habitability radii is in a separate bullet above. [[User:Praemonitus|Praemonitus]] ([[User talk:Praemonitus|talk]])

*The entire "Distance" section is a huge eyesore and frankly unimportant. Readers aren't going to care about every single distance estimate published, and are only going to care about the most accurate one, which is already present in the infobox. I'd remove the whole section.
:* I could see that each values makes the approximation more clear and shows the readers how they have tried to get the approximation of distance through parallax method. The whole section, similar to that of [[Approximations of π|pi]] can make it count. -[[User:The Herald|The Herald]] [[User talk:The Herald|<sup style="margin-left:0.5px">''the joy of the LORD''</sup>]][[Special:Contributions/The Herald|<sub style="margin-left:-47.5px">''my strength''</sub>]] 04:37, 19 March 2015 (UTC)
::*If I'm understanding you correctly, you're saying that the table helps show how the parallax method works. There's two things wrong with that: I don't see how the table conveys that at all, and such info would not be appropriate for this article but rather for the [[parallax]] article. The [[approximations of pi]] is different, since the increasing approximations of pi has been a subject of intense study itself, and well, pi is much more important to everyday life than this single star.

:::: I agree that the section isn't needed because all it conveys is the fact that the instrumentation is growing more accurate as time passes. It doesn't tell the reader anything new about the stars. If you absolutely have to retain it, I'd suggest moving it to the end of the article (as an appendix) so that it doesn't disrupt the flow.
