Steven Scott Vogt is an American astronomer of German descent whose main interest is the search for extrasolar planets. He is credited, along with R. Paul Butler, for discovering Gliese 581 g, the first potentially habitable planet outside of our own solar system.〔 He is a professor of astronomy and astrophysics at the University of California, Santa Cruz,〔(【引用サイトリンク】title= Steven S. Vogt - Professor, Astronomy & Astrophysics )〕 and is known worldwide for designing and building HIRES, a high-resolution optical spectrometer mounted permanently on the W. M. Keck Observatory 10-meter telescope on Mauna Kea, Hawaii. HIRES is an instrument critical to observations and discoveries about the planets, stars, galaxies, and the universe.〔(【引用サイトリンク】title= Outstanding Alumnus Award )〕 Vogt also built the Hamilton spectrometer at Lick Observatory (with which most of the first extrasolar planets were discovered).〔(【引用サイトリンク】title= Staff & Advisory Boards )〕 In 1987, earlier in his career, Vogt invented the technique of "Doppler imaging" for mapping the surface features of stars. Vogt is currently a member of the California-Carnegie Planet Search Team.〔 This team is building a new telescope in the Lick Observatory, the Automated Planet Finder, expected to be the most powerful in the world for detecting extrasolar planets. It will be able to track planets moving at velocities as little as 1 meter per second (the speed of a walking man).〔 Vogt and his team are credited with detecting a majority of the 100 planets now known.〔 Vogt received his bachelor's degrees in Physics and Astronomy from the University of California, Berkeley, in 1972, his Master of Science degree in Astronomy from UT Austin in 1976, and Ph.D in Astronomy from UT Austin in 1978. He's been a member of the University of California Observatories (UCO) at Lick Observatory since 1978.〔 ==Planets discovered== *55 Cancri f, with coauthors Debra Fischer, Paul Butler, Geoffrey Marcy (Vogt's first graduate student ), ''et al.'', published by Science Daily, 6 November 2007. * the controverted Gliese 581 g planet, with co-investigator Paul Butler, 29 September 2010. 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「Steven S.
