reviewing techniques and maintaining a list of identified planets.
The details of the
Terms of Reference
Definition of a "planet"
The WGESP developed a Working Definition
of a "planet", subject to change as we learn more about the population
of very low mass companions.
List of Planets
The WGESP developed a Working List
of extrasolar planet candidates, subject to revision. In most cases,
the orbital inclination of these objects is not yet determined, which
is why most should still be considered candidate planets.
Creation of IAU Commission 53 on Extrasolar Planets
The WGESP ended its six years of existence in August 2006, with
the decision of the IAU to create a new commission dedicated
to extrasolar planets as a part of Division III of the IAU.
The founding president of Commission 53 is Michael Mayor, in
honor of his seminal contributions to this new field of
astronomy. The Vice President is Alan Boss, and the Organizing
Committee members are Paul Butler, William Hubbard, Philip Ianna,
Martin Kürster, Jack Lissauer, Karen Meech, Francois Mignard,
Alan Penny, Andreas Quirrenbach, Jill Tarter, and Alfred Vidal-Madjar.
