This volume provides explanatory material, supplemental information, and detailed descriptions of the computational models and algorithms used to produce The Astronomical Almanac. It also offers complementary information that does not change annually, such as conceptual explanations, data, and bibliographic references. The level is scientifically technical but not expert, and should be usable by astronomers, engineers, navigators, surveyors, and others including general readers. Among the topics are relativity for astronomy, celestial mechanics, and metrology; terrestrial coordinates and the rotation of the Earth; orbital ephemerides of the Sun, Moon, and planets; eclipses of the Sun and Moon; and calendars. Earlier editions were published in 1961 and 1984. Annotation ©2013 Book News, Inc., Portland, OR (booknews.com)
This text provides detailed coverage of modern positional astronomy, including explanatory material, supplemental information and detailed descriptions of the computational models and algorithms used to produce The Astronomical Almanac. The 3rd edition of the Supplement has undergone significant revision to include new and updated content.
The Explanatory Supplement to the Astronomical Almanac offers explanatory material, supplemental information, and detailed descriptions of the computational models and algorithms used to produce The Astronomical Almanac, which is an annual publication prepared jointly by the US Naval Observatory and Her Majesty's Nautical Almanac Office in the UK.
The Explanatory Supplement to the Astronomical Almanac offers explanatory material, supplemental information, and detailed descriptions of the computational models and algorithms used to produce The Astronomical Almanac, which is an annual publication prepared jointly by the US Naval Observatory and Her Majesty's Nautical Almanac Office in the UK. Like The Astronomical Almanac, The Explanatory Supplement provides detailed coverage of modern positional astronomy. Chapters are devoted to the celestial and terrestrial reference frames, orbital ephemerides, precession, nutation, Earth rotation, and coordinate transformations. These topics have undergone substantial revisions since the last edition was published in 1992. Astronomical positions are intertwined with timescales and relativity in The Astronomical Almanac, so related chapters are provided in The Explanatory Supplement. The Astronomical Almanac also includes information on lunar and solar eclipses, physical ephemerides of solar system bodies, and calendars, so The Explanatory Supplement expounds upon each of these topics as well. The book is written at a technical, but non-expert level. As such, it provides an important reference for a full range of users including astronomers, engineers, navigators, surveyors, space scientists, and educators.
