| Jun 11, 2013 at 17:41 | comment | added | John Rennie | @Gugg: to be honest I don't really know. Possibly it's simply because R Doradus is in the southern hemisphere and traditionally all the big stellar interferometers have historically (I don't know I this is still the case) been in the northern hemisphere. Betelgeuse is a lot brighter than R Doradus, but I don't know how big a difference this makes for imaging studies. | |
