In 2006, Commission 53 on Extrasolar Planets was created from the Working Group on Extrasolar Planets (WGESP) at the IAU General Assembly in Prague, and approved for the next six years, the default extension for an IAU Commission. The WGESP was dissolved as a result. For information about the WGESP, please click on the image below:

Any IAU member who is interested in becoming a member of Commission 53 should write or e-mail the President of the Commission with a brief note regarding his/her interest in the work of the Commission.

The applicant will be provisionally accepted for membership and will thereafter be sent all communications. The application will be forwarded to the Organizing Committee and formal approval of the application will be made at the Commission business meeting at the following IAU General Assembly.

Applications for membership in the IAU are invited about a year before each General Assembly (the next General Assembly is in 2012), through the national Adhering Organizations. In the US, application forms are provided in the AAS Newsletter. Normally, minimum requirements are a Ph.D. plus 2-3 years experience in astronomical research resulting in a few publications in refereed journals, but it is up to the US National Committee to prioritize the applications they receive before making their proposals for membership to the IAU.
