This article seemed to say the Observatory has 135 employees and can only afford 2 astronomers. :/

Seems like you should try the method it on one of the classic CHARA datasets, either lambda and or zeta and. Is that in the works?

This is brilliant. So a few are close to terminator but not many. Does your database contain the full dataset, including cubesats put in non polar orbits?

Ahh yes. Indeed, Justin is working on that! I should check in on that. Also folks are working on HWO targets with CHARA.

If characterizing nearby hot stars is important, We should talk about a chara survey to look for faint companions. We can do delta mag 8 within 0.15” for bright stars with modest effort. Open time through noirlab

Would be interesting compare images using this novel polarization method with those by interferometry
See these images of same star by #VLTI

Best Ever Image of a Star’s Surface and Atmosphere - First map of motion of material on a star other than the Sun
Using ESO’s Very Large Telescope Interferometer astronomers have constructed the most detailed image ever of a star — the red supergiant star Antares. They have also made the first map of the velociti...
