The American Astronomical Society (AAS, sometimes spoken as "double-A-S"[ citation needed ]) is an American society of professional astronomers and other interested individuals, headquartered in Washington, DC. The primary objective of the AAS is to promote the advancement of astronomy and closely related branches of science, while the secondary purpose includes enhancing astronomy education and providing a political voice for its members through lobbying and grassroots activities. Its current mission is to enhance and share humanity's scientific understanding of the universe as a diverse and inclusive astronomical community.
The society was founded in 1899 through the efforts of George Ellery Hale. The constitution of the group was written by Hale, George Comstock, Edward Morley, Simon Newcomb and Edward Charles Pickering. These men, plus four others, were the first Executive Council of the society; Newcomb was the first president. The initial membership was 114. The AAS name of the society was not finally decided until 1915, previously it was the "Astronomical and Astrophysical Society of America". One proposed name that preceded this interim name was "American Astrophysical Society". [1]
The AAS today has over 8,000 members and six divisions – the Division for Planetary Sciences (1968), the Division on Dynamical Astronomy (1969), the High Energy Astrophysics Division (1969), the Solar Physics Division (1969), the Historical Astronomy Division (1980) and the Laboratory Astrophysics Division (2012). The membership includes physicists, mathematicians, geologists, engineers and others whose research interests lie within the broad spectrum of subjects now comprising contemporary astronomy. The annual meeting of the AAS is held in the spring and constitutes the largest gathering of astronomers, numbering over 3,000 in 2023. [2]
In 2019 three AAS members were selected into the tenth anniversary class of TED Fellows. [3]
The AAS established the AAS Fellows program in 2019 to "confer recognition upon AAS members for achievement and extraordinary service to the field of astronomy and the American Astronomical Society." [4] The inaugural class was designated by the AAS Board of Trustees and includes an initial group of 232 Legacy Fellows. [4] [5]
Because the field of astronomy is diverse, several divisions have been formed each of which promotes and enables a different branch of astronomy or astronomy-related science as well as working within the overall charter of the AAS. Many of the divisions hold separate meetings in addition to meeting with the main group. The divisions of the AAS, together with their main research interests, are:
Similar prizes are awarded by AAS divisions. These include:
The AAS also manages an International Travel Grant program, which any astronomer working in the US may apply to for travel to international astronomy-related conferences and other smaller grant and award programs. American Astronomical Society won the 2020 Webby People's Voice Award for Association in the category Web. [8]
The following past and present members served as president of the society during the listed periods: [9]
The Royal Astronomical Society (RAS) is a learned society and charity that encourages and promotes the study of astronomy, solar-system science, geophysics and closely related branches of science. Its headquarters are in Burlington House, on Piccadilly in London. The society has over 4,000 members, known as fellows, most of whom are professional researchers or postgraduate students. Around a quarter of Fellows live outside the UK.
Virginia Louise Trimble is an American astronomer specializing in the structure and evolution of stars and galaxies, and the history of astronomy. She has published more than 600 works in Astrophysics, and dozens of other works in the history of other sciences. She is famous for an annual review of astronomy and astrophysics research that was published in the Publications of the Astronomical Society of the Pacific, and often gives summary reviews at astrophysical conferences. In 2018, she was elected a Patron of the American Astronomical Society, for her many years of intellectual, organizational, and financial contributions to the society.
Eugene Newman Parker was an American solar and plasma physicist. In the 1950s he proposed the existence of the solar wind and that the magnetic field in the outer Solar System would be in the shape of a Parker spiral, predictions that were later confirmed by spacecraft measurements. In 1987, Parker proposed the existence of nanoflares, a leading candidate to explain the coronal heating problem.
Peter Goldreich is an American astrophysicist whose research focuses on celestial mechanics, planetary rings, helioseismology and neutron stars. He is the Lee DuBridge Professor of Astrophysics and Planetary Physics at California Institute of Technology. Since 2005 he has also been a professor at the Institute for Advanced Study in Princeton, New Jersey. Asteroid 3805 Goldreich is named after him.
Robert P. Kirshner is an American astronomer, Chief Program Officer for Science for the Gordon and Betty Moore Foundation, and the Clownes Research Professor of Science at Harvard University. Kirshner has worked in several areas of astronomy including the physics of supernovae, supernova remnants, the large-scale structure of the cosmos, and the use of supernovae to measure the expansion of the universe.
The Division for Planetary Sciences (DPS) is a division within the American Astronomical Society (AAS) devoted to Solar System research. It was founded in 1968. The first organizing committee members were: Edward Anders, Lewis Branscomb, Joseph W. Chamberlain, Richard M. Goody, John S. Hall, Arvidas Kliore, Michael B. McElroy, Tobias Owen, Gordon Pettengill, Carl Sagan, and Harlan James Smith. As of 2009, it is the largest special-interest division within the AAS. As of Oct 2010, membership totaled approximately 1415 planetary scientists and astronomers, including about 20% residing outside the U.S.
Scott Duncan Tremaine is a Canadian-born astrophysicist. He is a fellow of the Royal Society of London, the Royal Society of Canada and the National Academy of Sciences. Tremaine is widely regarded as one of the world's leading astrophysicists for his contributions to the theory of Solar System and galactic dynamics. Tremaine is the namesake of asteroid 3806 Tremaine. He is credited with coining the name "Kuiper belt".
Kenneth Charles Freeman is an Australian astronomer and astrophysicist who is currently Duffield Professor of Astronomy in the Research School of Astronomy and Astrophysics at the Mount Stromlo Observatory of the Australian National University in Canberra. He was born in Perth, Western Australia in 1940, studied mathematics and physics at the University of Western Australia, and graduated with first class honours in applied mathematics in 1962. He then went to Cambridge University for postgraduate work in theoretical astrophysics with Leon Mestel and Donald Lynden-Bell, and completed his doctorate in 1965. Following a postdoctoral appointment at the University of Texas with Gérard de Vaucouleurs, and a research fellowship at Trinity College, Cambridge, he returned to Australia in 1967 as a Queen Elizabeth Fellow at Mount Stromlo. Apart from a year in the Kapteyn Institute in Groningen in 1976 and some occasional absences overseas, he has been at Mount Stromlo ever since.
