1980 IAU Theory of Nutation: The final report of the IAU Working Group on Nutation

  • P. K. Seidelmann


In 1979 the Seventeenth General Assembly of the International Astronomical Union (IAU) in Montreal, Canada, adopted the 1979 IAU Theory of Nutation upon the recommendation of this Working Group. Subsequently the International Union of Geodesy and Geophysics (IUGG) passed a resolution requesting that this action be reconsidered in favor of a theory based on a different Earth model. As a consequence of that reconsideration the 1980 IAU Theory of Nutation was adopted. The details of that theory and the history of its adoption are described here in the Final Report of the IAU Working Group on Nutation. A summary of these events and the essence of our recommendations is provided first while the body of the report discusses these matters in greater detail. The theory itself is contained in Table I.
