Image of surface

So has someone imaged the surface of a non-main sequence star? Or is this statement as confusing as it seems? Maury (talk) 18:29, 7 August 2008 (UTC)[reply]

On 1. I answer "yes", on 2. "no". The first image ever of the surface of a star is over Betelgeuse, α Ori, the reknowned supergiant star. That image was produced by a more primitive interferometer. Said: Rursus (☻) 21:39, 15 December 2008 (UTC)[reply]

More images and results

this PDF lists and displays more than just Altair, that could be usable for the articles here on WP:

~~Figure for Regulus, on p33~~
~~Figure for Vega, on p34~~
Radius measurements on diverse M dwarfs A on p35-37
Radius measurements on Delta Cephei A on p38
Exact orbit determination on the Eta Orionis A component of Eta Orionis on p39-40
Disk around Be star Zeta Tauri on p42
Disk around Be star Gamma Cassiopeiae on p42
Exoplanet size measurements on HD 189733b on p44
Radius measurements on Mu Cassiopeiae A on p45
Image of Alderamin, on p51
Image of Rasalhague, on p51
Images of Beta Lyrae, on p54
Image of Zeta Andromedae, on p55
Image of Zeta Tauri Be star disk, on p55

To be used if possible. (The PDF eats my RAM) Said: Rursus (☻) 21:39, 15 December 2008 (UTC)[reply]

There's one trouble though. As much as I can find out, their copyright is the one of Georgia State University, which is of the kind: most rights reserved, but you may download one file copy to your own computer. Preferrably it would be better if CHARA array release some images to either Creative Commons Attribution 3.0 Unported (better) or Public Domain. Said: Rursus (☻) 08:59, 16 December 2008 (UTC)[reply]

Angular separation of Sheliak Aa1and Aa2?

The video of beta lyrae Aa1,2 is great but it unfortunately does not include a distance calibration (eg in microarcseconds). If the CHARA resolution is 200 microarcseconds, I would guess the maximum separation is around 1 milli-arcseconds.Paulhummerman (talk) 19:52, 24 October 2021 (UTC)[reply]
