David F. Gray
David F. Gray was an Astronomer and Stellar Spectroscopist who studies Stellar Atmospheres, Stellar Rotation, Magnetic cycles in Stars, and Stellar Granulation. He was the former director of the Elginfield Observatory before its closure and was a Professor Emeritus of Astronomy at the University of Western Ontario, London, Canada, where he has held positions since 1966.[1]
Career[edit]
Gray received his PhD in astronomy in 1966 from The University of Michigan[2]. He has served on, organized and chaired advisory committees for organizations such as the International Astronomical Union, the Canadian Astronomical Society, and the Canada-France-Hawaii Telescope. He was president of Commission 36 for the IAU, on the Theory of Stellar Atmospheres, between 1988 and 1991 and served on the observing-time allocation panel of the Hubble Space Telescope in 1996. He has published numerous papers in journals including The Astrophysical Journal, Publications of the Astronomical Society of the Pacific, The Astronomical Journal, Nature, and Solar Physics. He has written and contributed chapters to several books, including his own The Observation and Analysis of Stellar Photospheres which is a staple graduate textbook for Stellar Atmospheres. He has also edited three volumes of conference proceedings for the IAU and is a member of the Canadian Astronomical Society, the International Astronomical Union, the Astronomical Society of the Pacific, the Sigma Xi Honorary Society, and the American Astronomical Society.[3]
Research[edit]
Gray has worked on a number of areas of Stellar Astrophysics, such as the theory of stellar atmospheres and various properties of stars. His research papers include models of Stellar Photospheres, Spectral-Line analysis of Stars, Rotation Rates and Granulation. He has contributed greatly to the field of Stellar Atmospheres.[4]
