Inquiries or input to the IAU WGSN can be sent to iauwgsn@gmail.com. Before emailing the WGSN, please review our Terms of Reference to familiarize yourself with the group's activities and focus (names of stars already in common use or cultural/historical names for stars and asterisms from the world's cultures). As per IAU policy, the WGSN does not sanction the selling or buying of star names, nor recognize star names that have been bought or sold.

Important: The WGSN is NOT accepting proposals for NEW names for stars at this time. The WGSN *is* interested in new compilations of cultural star names, especially from difficult-to-find literature. The WGSN's activities between now and the IAU General Assembly in 2018 are centered on compiling traditional/common and cultural star names, adopting unique IAU names for bright and astrophysically important stars that already had traditional/common names (standardizing names and spellings, see IAU-CSN catalog), and discussing guidelines for the *future* naming of stars (beyond 2018).

Inquiries or comments unrelated to the WGSN's Terms of Reference may go unanswered.
