KY Cygni acutally is ~1000 solar radii based on newer luminosity

Estimates from Levesque _et al._ (2005) (like 1420 Rsol for KY Cyg) aren’t that accurate since they use questionable extinction estimates and poorly measured Mbols as far as I know

Alright.

@@Scuti2 Also, NML Cyg is ≲1350 Rsol based on a long baseline interferometry-derived angular diameter in the CHARM2 survey and its supposed distance. It is still likely to be lower than that value since it likely would have included its some parts of its complex dust shell. 1464 Rsol is derived from an effective temperature that most likely assumes a spherical dust shell, which is not the case.

Isn't that where the ~1,500 Rsol maximum star size came from, the rough average of the largest stars in that paper? If so, then that limit seems rather questionable.

@@goldsaturn1436 Don’t forget that the limit is also based on stellar evolutionary models. If it was only based on three or four stars it would be unreliable either way.
