Talk:Limb darkening

From Wikipedia, the free encyclopedia

It occyurs to me that another cause of limb darkening might be because faculae - particularly bright features on the solar photosphere - occur in the "canyons" between solar granules, and so when looked at from an angle they'd be partially obscured by the dimmer granule plasma. I have no idea how much of an effect this would have, though, so I'm reluctant to just toss this into the article itself. Bryan 04:05, 23 Jan 2005 (UTC)

I am more an instrument person, but I work with some of the best solar physicists, and I will ask them about that. Paul Reiser 05:58, 23 Jan 2005 (UTC)

[edit] What is a limb, anyways?

Hi. I came here trying to find out what Newton meant by superior limb of the sun as quoted in Webster (definition 1). The dab for limb has a picture but doesn't link here, so I linked it here. Should there be a Limb (astronomy) as suggested by the dab page, or should it be part of this page, perhaps with the picture of the moon? But the moon isn't really a star… so, it doesn't experience limb darkening (oops). Or does it? But I'm not here to ask an astronomy question, I'm here to discuss how to improve the articles. I'll try to fix the dab so it doesn't imply that the moon is a star. 「ѕʀʟ·✎」 10:08, 31 December 2007 (UTC)

Phases of Venus mentions 'apparent disk' and moon mentions the 'limbs' which links to wiktionary (??). 「ѕʀʟ·✎」 10:17, 31 December 2007 (UTC)
