David Ciardi
David Robert Ciardi (born 17 July 1969) is an American astronomer. He received a bachelor's degree in physics and astronomy from Boston University in 1991, and a Ph.D. in physics from the University of Wyoming in 1997. Career Ciardi has published refereed journal articles across a wide range of topics, including exoplanets, star formation, interstellar dust, molecular clouds, and evolved stars. His observations of Vega using long-baseline interferometry with the Palomar Testbed Interferometer were the first to spatially resolve the debris disk around this star and to show that dust was present within 1 AU of the star - akin to the interplanetary dust in the Solar System that produces the zodiacal light. This work led to the discovery of dust in the inner regions around other stars and leading to the discovery of a gap between the inner dust ring and the outer dust ring in many systems - the existence of which is still not understood. Ciardi is a member of the Kepler Science Team ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 a ...

Wide Field Infrared Explorer
Wide-field Infrared Explorer (WIRE, also Explorer 75 and SMEX-5) was a NASA satellite launched on 5 March 1999, on the Pegasus XL launch vehicle into polar orbit between above the surface of Earth. WIRE was intended to be a four-month infrared survey of the entire sky at 21-27 µm and 9-15 µm, specifically focusing on starburst galaxies and luminous protogalaxies. WIRE had problems and was unable to carry out its IR survey, and was deactivated on 30 September 2000, and finally reentered and burned up in 2011. Science The science team was based at the Infrared Processing and Analysis Center (IPAC) in Pasadena, California. Flight operations, integration, and testing were from Goddard Space Flight Center in Maryland. The telescope was built by Space Dynamics Laboratory in Utah. Premature ejection of the spacecraft aperture cover led to depletion of the solid hydrogen shortly after launch, ending the primary science mission. The onboard star tracker remained functiona ...

William Allis
William Phelps Allis (November 15, 1901 – March 5, 1999) was an American theoretical physicist specializing in electrical discharges in gases. He was the grandson of Edward P. Allis,Morse, 1967 p. 100 founder of the E.P. Allis Company, which became Allis-Chalmers. Education Allis majored in school and received his S.B. in 1923 and S.M. in 1924 from the Massachusetts Institute of Technology (MIT). He was granted his ''Docteur ès science'' (Sc.D.) in physics, in 1925, from the University of Nancy, France. From 1925 to 1929, he was a research associate at MIT. It was there that he met Philip M. Morse. Morse, at the suggestion of Karl T. Compton, made arrangements for postdoctoral studies and research with Arnold Sommerfeld at the Ludwig Maximilian University of Munich in 1930 and at the University of Cambridge in the spring and summer of 1931. Allis went with Morse to Munich and Cambridge. [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Martin Harwit
Martin Otto Harwit (born 9 March 1931) is a Czech-American astronomer and author known for his scientific work on infrared astronomy as a professor at Cornell University. He was later director of the National Air and Space Museum in Washington, D.C. from 1987 to 1995. Career He attended Oberlin College for his B.A. in physics, and earned a master’s degree from the University of Michigan after which he was awarded a Ph.D in physics by Massachusetts Institute of Technology in 1960. That same year he was granted a NATO postdoctoral fellowship at Cambridge University, followed in 1961 by a (US) National Science Foundation postdoctoral fellowship at Cornell University, Ithaca, New York, In 1962 he joined the astronomy faculty at Cornell and was later appointed professor. His main interest lay in the building of telescopes to observe infrared radiation from space, which required the telescopes to be launched into orbit. He designed, built and launched the first rocket-po ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cornell University
Cornell University is a private statutory land-grant research university based in Ithaca, New York. It is a member of the Ivy League. Founded in 1865 by Ezra Cornell and Andrew Dickson White, Cornell was founded with the intention to teach and make contributions in all fields of knowledge—from the classics to the sciences, and from the theoretical to the applied. These ideals, unconventional for the time, are captured in Cornell's founding principle, a popular 1868 quotation from founder Ezra Cornell: "I would found an institution where any person can find instruction in any study." Cornell is ranked among the top global universities. The university is organized into seven undergraduate colleges and seven graduate divisions at its main Ithaca campus, with each college and division defining its specific admission standards and academic programs in near autonomy. The university also administers three satellite campuses, two in New York City and one in Educatio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Judy Pipher
Judith Lynn Pipher (, June 18, 1940 – February 21, 2022) was a Canadian-born American astrophysicist and observational astronomer. She was Professor Emerita of Astronomy at the University of Rochester and directed the C. E. K. Mees Observatory from 1979 to 1994. She made important contributions to the development of infrared detector arrays in space telescopes.

Minor Planet Circulars
The Minor Planet Center (MPC) is the official body for observing and reporting on minor planets under the auspices of the International Astronomical Union (IAU). Founded in 1947, it operates at the Smithsonian Astrophysical Observatory. Function The Minor Planet Center is the official worldwide organization in charge of collecting observational data for minor planets (such as asteroids), calculating their orbits and publishing this information via the '' Minor Planet Circulars''. Under the auspices of the International Astronomical Union (IAU), it operates at the Smithsonian Astrophysical Observatory, which is part of the Center for Astrophysics along with the Harvard College Observatory.
