Qualification for Membership and Application Procedure
Membership in the IAU is open to countries (National Membership) and individuals (Individual or Junior Membership). The procedures for submission and approval of applications in the two categories are described in the IAU Working Rules (§ II and III ). A brief summary of the procedure for seeking nomination for IAU Individual or Junior Membership is given below.
Please note that a new category of membership, the Junior Member has been approved at the IAU XXX General Assembly (August 2018). Now researchers who have just completed their PhD in a branch of astronomy/astrophysics can be proposed as IAU Junior Member. The admission of new Junior Members will be evaluated annually by the Membership Committee and approved by the Executive Committee. Junior Membership is temporary and cannot be extended for more than six years.
- IAU Individual Membership or Junior Membership: Nomination of a candidate residing in a non-Member country
Nomination for IAU Individual or Junior Membership by a qualified astrophysicist residing in a country which is not National Member of the IAU can be applied for by contacting the NCA or Adhering Organization in a neighboring IAU National Member country. The individual may request to receive the appropriate application link, following all instructions and deadlines given above, or by contacting one of the IAU Division Presidents.
