Proposed names
HD 81688 HD 81688 b
The name of Chiba Prefecture, located north east of Tokyo, comes from the feudal lord Chiba established around four hundred years ago. The Chiba clan chose the Big Dipper and the polar star for the crest designed as “Kuyoumon” (literally nine stars). The center is the polar star and the surroundings are the Big Dipper. Chiba Shusaku, the great swordsman, created the sword school “Hokushin-Ittouryuu”, and “Hokushin” means the Big Dipper and the polar star.  We propose the name “CHIBA” for the central star HD81688, because this is apparently one of the closest Exoworlds to the Big Dipper.

Mysdia (sign in to vote)
Rosalind Franklin's x-ray crystallography work played a large role in determining the structure of DNA, the molecule from which all life finds itself derived. Rosalind's contributions to the fields of both biology and biochemistry, while not fully recognized until after her death, affirm her place among the 'greats' of science, not to mention her role as an inspirational figure for women in the sciences. Naming a foreign star after such an individual would serve as a testament to her contributions to science, as well as a reminder to future aspiring scientists to never stop asking questions, to never stop moving forwards.
