It is a Carol Doak pattern. The quiltmaker called it "Rainbow Stars" but I don't know if that's what Carol called it, also.

It's of interest to note the comment on the post the OP linked to. That person asked about a pattern to the paper pieced "butterfly". So maybe Carol designed a butterfly and not a star...?
