Good article
This article read well, was well structured, had a good lead, and was broad in scope. It meets all of the GA criteria... Johnfos 10:00, 31 August 2007 (UTC)

Rotational Speed of the sun
According to my calculation, the rotational speed (at the equator) of the sun is (((4 379 000km / 25 days) / 24) / 60) / 60 = 2.03 km/sec. But the table in this article quotes a G0 star as rotating at 12 km/sec. (the sun is G2). Is the sun so unusual??? Geoffrey.landis (talk) 17:21, 28 November 2008 (UTC)
- 12 km/s matches the value in the reference (#16). So I would say... possibly.—RJH (talk) 23:06, 28 November 2008 (UTC)
Microturbulence
Microturbulence in a star? What is this? Coronellian (talk) 19:58, 11 October 2009 (UTC)
- I believe it is small scale turbulence on the photosphere. You might want to take a look at the "microturbulence" article.—RJH (talk) 14:54, 12 October 2009 (UTC)
rotational braking confusion
Under rotational braking it says "As the expected life span of a star decreases with increasing mass, this can be explained as a decline in rotational velocity with age." This seems to be confusing association with cause. The expected life of a star decreases with larger mass due to faster rate of fusion. Better to just delete the whole sentence from this section ? - Rod57 (talk) 09:44, 14 July 2014 (UTC)
But... why?
Why do stars rotate? think this very pertinent question goes unanswered in the article. Did I miss something? Jyg (talk) 04:51, 6 January 2015 (UTC)
Planets
Does stellar rotation ever correlate with planetary orbits? Kortoso (talk) 23:20, 6 January 2016 (UTC)
2018 results unexpected
[1] reports on Asteroseismic detection of latitudinal differential rotation in 13 Sun-like stars quote "We report the measurement using asteroseismology of latitudinal differential rotation in the convection zones of 40 Sun-like stars. For the most significant detections, the stars’ equators rotate approximately twice as fast as their midlatitudes. The latitudinal shear inferred from asteroseismology is much larger than predictions from numerical simulations." - Rod57 (talk) 13:22, 30 September 2018 (UTC)
