Gerard Theodore van Belle (born 1968, in Tallahassee, FL) is an American-Canadian astronomer. He received a bachelor's degree in physics from Whitman College in 1990, a master's in physics from The Johns Hopkins University in 1993, and a Ph.D. in physics from the University of Wyoming in 1996. While at Whitman College, he initiated as a member of the Sigma Chi fraternity. Dr. van Belle is an expert in near-infrared interferometry, and has utilized this technique to measure the sizes of hundreds of nearby stars . The first direct measurement of stellar shape was carried out by a team led by him using the Palomar Testbed Interferometer to make observations of the rapidly rotating star Altair. Dr. van Belle has also contributed to practical considerations of operating astronomical interferometers, particularly regarding considerations of calibration of these complicated instruments . After schooling, Dr. van Belle took a position at the Jet Propulsion Laboratory as an instrument architect for NASA's Keck Interferometer, and later joined the Michelson Science Center (now NASA Exoplanet Science Institute) at Caltech in 2003. He has participated in the commissioning of the Palomar Testbed Interferometer, and the CHARA Array. In 2007, he became a member of the astronomy faculty at the European Southern Observatory (ESO), and instrument scientist for the PRIMA instrument of ESO's VLTI facility; later in early 2011 he was also appointed instrument scientist for the MATISSE instrument of the VLTI. Since August 2011 he has been a member of the astronomer faculty at Lowell Observatory. Dr. van Belle is currently serving as President of the International Astronomical Union's Commission 54 on Optical and Infrared Interferometry, for 2012-2015. Asteroid 25155 van Belle is named for him. == References == 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Gerard van Belle」の詳細全文を読む スポンサード リンク
