Nicole Capitaine (born Nicole Taton; March 14, 1948) is an astronomer at the Paris Observatory who is known as an expert on astrometry and related standards. [1]
In 1969, Capitaine received a bachelor's degree ("licence") from the Faculty of Sciences in Paris in mathematics. (She was thus one of the last graduates of this subdivision of the university before its re-organization in the wake of the Paris disturbances of 1968.) In 1970 she graduated with a degree in astronomy from Pierre and Marie Curie University. The same year she joined the Paris Observatory as an assistant. She then held several positions there before becoming an astronomer in charge of research. In 1972, she received a PhD in astronomy at the Pierre and Marie Curie University. In 1982, she wrote her habilitation thesis, giving her the status of direct researcher.
Capitaine became deputy director of the Department of Fundamental Astronomy at the Paris Observatory in 1985. She became the director in 1993. Her scientific activity was carried out mainly within the framework of the Space Geodesy Research Group (GRGS), as well as various working groups of the International Astronomical Union. In 2002, still at the Paris Observatory, she became a full-time astronomer in the SYRTE department (Space Time Reference Systems). In 2013, she retired and became an emeritus astronomer.
Her work, carried out in the framework of a large international cooperation, led to a better definition of reference systems and time scales for astronomy, as well as to a better knowledge of the rotation of the Earth. They have also led to the adoption by the IAU and IUGG (International Geodesic and Geophysical Union) of new parameters and models for astronomy and geodesy, which are essential for many applications to space dynamics and the dynamics of the solar system.

The International Astronomical Union is an international non-governmental organization (INGO) with the objective of advancing astronomy in all aspects, including promoting astronomical research, outreach, education, and development through global cooperation. It was founded on 28 July 1919 in Brussels, Belgium and is based in Paris, France.
The Paris Observatory, a research institution of the Paris Sciences et Lettres University, is the foremost astronomical observatory of France, and one of the largest astronomical centers in the world. Its historic building is on the Left Bank of the Seine in central Paris, but most of the staff work on a satellite campus in Meudon, a suburb southwest of Paris.
The Bureau des Longitudes is a French scientific institution, founded by decree of 25 June 1795 and charged with the improvement of nautical navigation, standardisation of time-keeping, geodesy and astronomical observation. During the 19th century, it was responsible for synchronizing clocks across the world. It was headed during this time by François Arago and Henri Poincaré. The Bureau now functions as an academy and still meets monthly to discuss topics related to astronomy.
The Santa Lucia Stroncone Astronomical Observatory is an astronomical observatory located at 350 metres (1,150 ft) altitude in Stroncone, near the city of Terni, in Umbria, north central Italy.
The Paris meridian is a meridian line running through the Paris Observatory in Paris, France – now longitude 2°20′14.02500″ East. It was a long-standing rival to the Greenwich meridian as the prime meridian of the world. The "Paris meridian arc" or "French meridian arc" is the name of the meridian arc measured along the Paris meridian.
The Central Bureau for Astronomical Telegrams (CBAT) is the official international clearing house for information relating to transient astronomical events.
Victor A. Brumberg is a Russian theoretical physicist specializing in relativistic celestial mechanics and astrometry. He worked as a chief-scientist at the Institute of Applied Astronomy, Russian Academy of Sciences, St. Petersburg. He is noted for his work on general relativity applied to celestial mechanics and ephemerides. He is currently living in the United States of America.
Catherine Jeanne Cesarsky is an Argentine and French astronomer, known for her research activities in astrophysics and for her leadership in astronomy and atomic energy. She is the current chairperson of the Square Kilometre Array's governing body, SKAO Council. She was the first female president of the International Astronomical Union (2006-2009) and the first female director general of the European Southern Observatory (1999-2007).
Elena Vladimirovna Pitjeva is a Russian astronomer working at the Institute of Applied Astronomy, Russian Academy of Sciences, St. Petersburg. She has published over 100 articles, as listed in Google Scholar and the Astrophysics Data System in the field of solar system dynamics and celestial mechanics.
Jean-Claude Pecker was a French astronomer, astrophysicist and author, member of the French Academy of Sciences and director of the Nice Observatory. He served as the secretary-general of the International Astronomical Union from 1964 to 1967. Pecker was the President of the Société astronomique de France (SAF), the French amateur astronomical society, from 1973–1976. He was awarded the Prix Jules Janssen by the French Astronomical Society in 1967. A minor planet is named after him. Pecker was a vocal opponent of astrology and pseudo-science and was the president of the Association française pour l'information scientifique (AFIS), a skeptical organisation which promotes scientific enquiry in the face of quackery and obscurantism.
Athena Coustenis is an astrophysicist specializing in planetology. Dr. Coustenis, a French national, is director of research, Centre national de la recherche scientifique, at LESIA, at the Paris Observatory, Meudon. She is involved in several space mission projects for the European Space Agency (ESA) and for NASA. Her focus is on gas giant planets Saturn, Jupiter and their moons, and she is considered a foremost expert on Saturn's moon Titan.
María Assumpció Català i Poch was a Spanish professor, mathematician, and astronomer. She taught from 1952 to 1991. She started as an assistant in the Astronomy Section of the Seminar on Mathematics in Barcelona, related to the Spanish National Research Council. Later, she worked in the Henri Poincaré Institute and she also cooperated in some projects with the special chair of Technology in the Polytechnic University of Catalonia.
Sidney Carne Wolff is an American astrophysicist, researcher, public educator, and author. She is the first woman in the United States to head a major observatory, and she provided significant contributions to the construction of six telescopes. Wolff served as Director of the Kitt Peak National Observatory (KPNO) and the National Optical Astronomy Observatory (NOAO). She is a member of the International Astronomical Union's Division G: Stars and Stellar Physics.
Véronique Dehant is a Belgian geodesist and geophysicist. She specializes in modeling the deformation of the Earth's interior in response to the planet's rotation and the gravitational forces exerted upon it by the Sun and Moon. She has used similar techniques to study Mercury, Venus, Mars and the icy satellites of the outer planets. She primarily works at the Royal Observatory of Belgium, but also serves as an Extraordinary Professor at the Université Catholique de Louvain.
