...but to say you "cannot find any" when Wikipedia has a few does not suggest your search was very thorough.
I agree, my
"research" (that is if one actually considers a Google or Wikipedia search as "research"

) was not thorough.
However, my statement was predominantly referring to the context of the discussion; specifically that Wonder Womans red star had context as pertains to WWII America. Nothing I've found, including the page on Wikipedia you provided, makes any such
obvious link. So, within the context of this discussion, I'm not quite sure what point you're trying to make?
Was Wonder Woman wearing a red star on her headband because it was a part of the flag of Birmingham, Alabama?...or a variant on the flag of the President
from 1912?...or part of the flag of Washington DC (where it's not one prominent star but three small ones with two prominent stripes)?
I'm pretty sure that it isn't.
Was it because the U.S. National Christmas tree star is
occasionally red?
Since there's no tradition of it being any specific color, I'd say that's also out as the inspiration.
There's also no record or reference of a red star being used as a common or uncommon, American patriotic symbol, during WWII.
So why is it red?
Some sources claim that it's purpose is to symbolize her allegiance and patriotism to the Amazonians, others that it simply represents her dedication to freedom in general. The red, white and blue motif of her costume is obvious, especially considering the time of her creation (1941). But typically, stars with specific "American" conotations are almost always white...as represented by the other stars on her costume. Since Wonder Woman is an Amazonian Princess (royalty) the tiara being gold is also obvious (symbolizing a royal crown). So, most likely, the star on her tiara being colored red is less to do with any specific symbolism for the color, and is more likely that a white star on a gold background would have simply been washed out or lost in contrast in a color inked comic book - therefore a prominent and contrasting color was used that would stand out: red.
As an aside (but I hope at least an
interesting aside), the inspiration for Wonder Womans Golden Lasso was two fold. One, the creator of Wonder Woman, William Moulton Marston, wanted a strong female super-hero that was the equal of other contemporary hero's (such as Super Man), but could fight evil without having to always resort to fists (like all of the
male super heroes). Secondly and most importantly though, William Moulton Marston was also the inventor of the polygraph.
