Commissions
Activities in the various astronomical sub-disciplines are mostly conducted by Commissions, coordinated through the IAU Scientific Divisions which steer the activities and evolution of their Commissions.
Depending on their structure, Commissions are classifies as:
- Inter-Division Commissions
- Cross-Division Commissions
Individual and Junior Members of the Union may join or leave a Commission at any time, while belonging to no more than three Commissions (joining a fourth Commission is allowed if the latter belongs to Division B or C). In order to join a Commission, please contact the Commission President and the IAU Secretariat.
