Hi Dan,
Check the Interferometry Paper.
https://portfolio.du.edu/pc/port.detail?id=177813
They actually imaged the star and disk (at nearly 2,000 light years).
The Mt Wilson system can resolve a nickel at 10,000 miles. I don't
think the JWST can come close to that. The CHARA is the eqivalent of a
1,000 foot, 12,000 inch telescope.
Once the eclipse is over since the eclipsing body does not radiate, it
cannot be seen.
