Divisions

Activities in the various astronomical sub-disciplines are mostly coordinated through the IAU Divisions.

Following the adoption of the Executive Committee Resolution at the XXVIIIth General Assembly held in Beijing, a new Division scheme has been put into place, to take into account the evolution of astronomy and to reflect the scientific policy of the IAU.

These Divisions will include one or more IAU Commissions, each focusing on a narrower scientific or organizational theme. The relation between the existing Commissions and the new Divisions will be gradually established in the coming months.

For information on joining Divisions please see: IX. TERMS OF REFERENCE FOR DIVISIONS

The list of Divisions adopted in Beijing is as follows:

• Division A Fundamental Astronomy
• Division B Facilities, Technologies and Data Science
• Division C Education, Outreach and Heritage
• Division D High Energy Phenomena and Fundamental Physics
• Division E Sun and Heliosphere
• Division F Planetary Systems and Astrobiology
• Division G Stars and Stellar Physics
• Division H Interstellar Matter and Local Universe
• Division J Galaxies and Cosmology
