Gilles Chabrier
Gilles Chabrier is a French astrophysicist who is best known for his work on brown dwarfs. He is currently a professor of astronomy at the University of Exeter. Life and scientific work Chabrier studied physics at the École normale supérieure de Lyon (ENS) in Lyon. After completing his PhD he continued his research at the University of Rochester. In the early 1990s he built up a research group at the ENS Lyon in collaboration with the nearby Lyon Observatory. In 1995, the Centre de recherche astronomique de Lyon was founded, known as the Centre de Recherche Astrophysics Lyon (CRAL) since 2007. Chabrier continues to lead one of the research groups at CRAL. He is also a research director at the Centre national de la recherche scientifique (CNRS). Before the discovery of brown dwarfs in 1995, Chabrier helped develop the theory of their structure in collaboration with Isabelle Baraffe, France Allard and Didier Saumon Awards * 2006 CNRS Silver Medal * 2010 Jean Rica ...

University Of Exeter
The University of Exeter is a public university , public research university in Exeter, Devon, England, United Kingdom. Its predecessor institutions, St Luke's College, Exeter School of Science, Exeter School of Art, and the Camborne School of Mines were established in 1838, 1855, 1863, and 1888 respectively. These institutions later formed the University of Exeter after receiving its royal charter in 1955. In Post-nominal letters, post-nominals, the University of Exeter is abbreviated as ''Exon.'' (from the Latin ''Exoniensis''), and is the suffix given to Honorary Degree, honorary and academic degrees from the university. The university has four campuses: Streatham Campus, Streatham and St. Luke's Campus, St Luke's (both of which are in Exeter); and Truro and Penryn Campus, Penryn (both of which are in Cornwall).

Gold Medal Of The Royal Astronomical Society
The Gold Medal of the Royal Astronomical Society is the highest award given by the Royal Astronomical Society (RAS). The RAS Council have "complete freedom as to the grounds on which it is awarded" and it can be awarded for any reason. Past awards have been given for "outstanding personal researches in the fields of astronomy and geophysics" as well as general contributions to astronomy and geophysics "that may be made through leadership in research programmes, through education and through scientific administration". It has been awarded both for research that has taken a lifetime (it has most frequently been given to recognise an extraordinary lifetime achievement), and for specific pieces of research. History The RAS was founded in 1820 and the first Gold Medals were awarded in 1824. Silver medals were also awarded in 1824 and 1827, but that practice was quickly abandoned, instead the RAS established other awards. In the early years, more than one medal was often awarded in a ...

Observertoire De Lyon
Lyon Observatory is located in Saint-Genis-Laval, a commune in the Rhône department in eastern France, near Lyon. Founded in 1878, the entire facility was listed as a historical site on May 9, 2007. In 1867, Paris astronomer Charles André requested of the prefect of Rhone, that a new observatory be created. In 1873, a commission offered to establish a facility in Sainte-Foy-lès-Lyon. André sought to have the site built in Saint-Genis-Laval. On March 11, 1878, Patrice de MacMahon approved the creation of the Lyon Observatory. André was appointed its first director. Research Lyon Observatory has worked on polychromatic artificial stars for adaptive optics systems, made by a laser.

Brown Dwarfs
Brown dwarfs (also called failed stars) are substellar objects that are not massive enough to sustain nuclear fusion of ordinary hydrogen ( 1H) into helium in their cores, unlike a main-sequence star. Instead, they have a mass between the most massive gas giant planets and the least massive stars, approximately 13 to 80 times that of Jupiter (). However, they can fuse deuterium ( 2H), and the most massive ones (> ) can fuse lithium ( 7Li). Astronomers classify self-luminous objects by spectral class, a distinction intimately tied to the surface temperature, and brown dwarfs occupy types M, L, T, and Y. As brown dwarfs do not undergo stable hydrogen fusion, they cool down over time, progressively passing through later spectral types as they age. Despite their name, to the naked eye, brown dwarfs would appear in different colors depending on their temperature. The warmest ones are possibly orange or red, while cooler brown dwarfs would likely appear magenta or black to the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
École Normale Supérieure De Lyon
The École normale supérieure de Lyon (also known as ENS de Lyon, ENSL or Normale Sup' Lyon) is a French grande école located in the city of Lyon. It is one of the four prestigious écoles normales supérieures in France. The school is composed of two academic units— Arts and Sciences— with campuses in Lyon, near the confluence of the Rhône and Saône rivers. ENSL's students usually enjoy a special civil servant status in the wake of highly competitive exams, providing they pursue careers in public service. Although it maintains extensive connections with the University of Lyon and external research institutions, including the CNRS, the school remains independent. History Training teachers for normal schools ''L'École normale supérieure de Lyon'' is the descendant of two top educational institutions founded by Jules Ferry: *''L'École normale supérieure de Fontenay-aux-Roses'', for girls, founded in 1880. *''L'École normale supérieure de Saint-Cloud'', for b ...

Astrophysics
Astrophysics is a science that employs the methods and principles of physics and chemistry in the study of astronomical objects and phenomena. As one of the founders of the discipline said, Astrophysics "seeks to ascertain the nature of the heavenly bodies, rather than their positions or motions in space–''what'' they are, rather than ''where'' they are." Among the subjects studied are the Sun, other stars, galaxies, extrasolar planets, the interstellar medium and the cosmic microwave background. Emissions from these objects are examined across all parts of the electromagnetic spectrum, and the properties examined include luminosity, density, temperature, and chemical composition. Because astrophysics is a very broad subject, ''astrophysicists'' apply concepts and methods from many disciplines of physics, including classical mechanics, electromagnetism, statistical mechanics, thermodynamics, quantum mechanics, relativity, nuclear and particle physics, and atomic and m ...
