Let me tell you about our suggestion from Jonan High School Science Club.
We have discussed about Name ExoWorlds, and since the star named Delphinus 18 is relatively easy to be observed with the naked eye or binoculars from Tokushima Prefecture, we chose this star, which is not so famous as Pollux and Fomalhaut (We thought that there were fewer rivals).
Another reason why we chose this star is that its planet was found at a Japanese astronomical observatory.
We originally were going to propose "Bizan*" and "Yoshinogawa*" (the name of place which symbolized our hometown) or "Sudachi*" (the special agricultural product in our hometown).
However, these names have been already used for the names of minor planets.
Therefore, we decided to look for the names related to Greek Myths because many Japanese people are familiar with Greek Myths.
"Arion", the main character of a Greek myth related to Delphinus is not used for celestial bodies, and, we proposed Arion for the name of the exoplanet.
We proposed "Musica" for its host star, which means music in Latin language, because music connects Arion and the dolphin in the Greek Myth.
We also thought that not-local (not-Japanese) names are good for appealing to the world.
We appreciate everyone who voted to our proposed names.
