"as large as one astronomical unit"

Probably meant to say "in radius", but the naïve might assume "in diameter." This is vague at best and wrong at worst, since isn't even Sol expected to get bigger than 1AU radius in several billion years? --Polymath69 13:33, 17 August 2007 (UTC)

"surficide reactions"? - wouldn't surface chemical reactions be better? As it is, it sounds like your talking about the results of murdering surfers. 144.137.116.114 (talk) 07:23, 17 May 2008 (UTC)Jim Jacobs.

Apparent contradiction

The diagram in this article shows stars moving horizontally from the main sequence to supergiant status. The diagram shown in most of the other articles, e.g. giant star, shows the supergiants far higher in absolute magnitude. Please reconcile or clarify this. Wnt (talk) 05:21, 30 June 2008 (UTC)

The supergiants are in roughly the same position in both diagrams. In Image:Stellar evolutionary tracks-en.svg, the luminosity of the 15 solar-mass track is shown as approximately 3ċ10 solar luminosities. In Image:HR-diag-no-text-2.svg, the absolute magnitude of luminosity class Ia is shown as around −7. Since 4.83 − 5 log100 (3ċ10) = −6.36, you can see that the positioning is approximately the same.
