Toward a Common Language: The Washington Multiplicity Catalog
NAVAL OBSERVATORY WASHINGTON DC
Pagination or Media Count:
Due to improvements in technology interferometers, precision radial-velocity techniques, etc., the traditional separationperiod regimes of wide and close binaries are witnessing increasing overlap. This is expected to lead to increasing confusion in component identification, since different observing techniques adopted their own rules for designation of these components. A quick overview will be given of the Washington Multiplicity Catalog, an effort to create a common nomenclature scheme for all types of stellar and sub-stellar companions.
