Lisa Kaltenegger is an Austrian astronomer with expertise in the modeling and characterization of exoplanets and the search for life. On July 1, 2014, she was appointed Associate Professor of Astronomy at Cornell University.〔http://news.cornell.edu/stories/2014/06/lisa-kaltenegger-searches-another-pale-blue-dot Cornell Chronicle, 25 June 2014〕 Previously, she held a joint position at the Max Planck Institute for Astronomy in Heidelberg where she was the Emmy Noether Research Group Leader for the "Super-Earths and Life" group, and at the Harvard-Smithsonian Center for Astrophysics in Cambridge, MA.〔http://www.nature.com/naturejobs/science/articles/10.1038/nj7395-555a Nature Magazine, 25 April 2012〕 She was appointed Lecturer in 2008 at Harvard University and 2011 at University of Heidelberg.〔http://ostaustria.org/bridges-magazine/volume-20-december-22-2008/item/3756-introducing-astrophysicist-lisa-kaltenegger-simulating-worlds-stranger-than-fiction Bridges, Vol. 20, December 2008〕 ==Academic career== Kaltenegger earned a degree in astrophysics in 1999 from Karl Franzens University in Graz, Austria; a master’s in physics and engineering in 2001 from the Graz University of Technology; and a doctorate in astrophysics in 2005 from Karl Franzens University.〔http://astrobiology.nasa.gov/directory/people/kaltenegger-lisa/ NASA〕 Her Ph.D. was awarded sub auspiciis praesidentis rei publicae by the Austrian president.〔http://ostaustria.org/bridges-magazine/volume-20-december-22-2008/item/3756-introducing-astrophysicist-lisa-kaltenegger-simulating-worlds-stranger-than-fiction Bridges, Vol. 20, Dec. 2008〕 Kaltenegger is known for her studies of the atmospheres of extrasolar planets, especially Earth-like ones 〔(【引用サイトリンク】 url=http://content.time.com/time/magazine/article/0,9171,2161680,00.html )〕〔(【引用サイトリンク】 url=http://www.zeit.de/2012/24/Forschung-Exoplaneten )〕 and is a pioneer in the study of the Earth as an astronomical object evolving in time. She studied the change in the Earth's spectral fingerprint as a comparison with the evolutionary stages of Earthlike exoplanets to generate an "Alien ID Chart" 〔(【引用サイトリンク】url=http://www.smithsonianmag.com/special-section-innovators/signs-of-life-167320708/ )〕 〔(【引用サイトリンク】url=http://arxiv.org/abs/astro-ph/0609398 ) article on Spectral Evolution of an Earth-like planet through geological time〕 - pointing out that as biology and geology change the Earth through the ages, its appearance to a telescope observing it from distant stars would also change. She also investigated the ability of future telescopes like the James Webb Space Telescope to detect evidence of life using spectral biomarkers (biosignatures) 〔(【引用サイトリンク】 url=http://arxiv.org/abs/0903.3371 )〕 and generated the first spectra of Earth seen as a transiting exoplanet in 2009 〔http://arxiv.org/abs/0903.3371 Earth seen as a transiting planet〕 concluding that it will be a hard problem for JWST and bigger future telescopes are needed to find signatures of life on many planets. In 2009 she discussed how one can determine habitability for moons around giant planets 〔(【引用サイトリンク】url=http://www.space.com/7709-moons-avatar-pandora.html ) Moons life Avatar could be habitable〕〔(【引用サイトリンク】 url=http://arxiv.org/abs/0912.3484 )〕 coinciding with the suggestion of such a moon in the movie Avatar (2009 film). Super-volcanoes on exoplanets:〔(【引用サイトリンク】title=Can We Spot Volcanoes on Alien Worlds? Astronomers Say Yes. | www.cfa.harvard.edu/ )〕 In 2010 she explored whether we could observe geological activity, that is very important for habitability, on exoplanets, finding that about 10 times Pinatubo eruptions could be detected around the closest exoplanets, showing us if other planets are similar to our own Earth. 2011 she led a team to model the spectral fingerprint of Gliese 581 d,〔(【引用サイトリンク】 title=The Twin Earths of Gliese 581: Two Exoplanets May Support Life - SPIEGEL ONLINE )〕 one of the first small Radial Velocity planets to be discovered in the habitable zone of its star. In 2013 she was part of the team announcing the discovery of the first two potentially habitable Kepler planets, with radii smaller than 2 Earth radii in the habitable zone of their stars, Kepler 62e and Kepler 62f 〔(【引用サイトリンク】title=Kepler Makes Discoveries Inside the Habitable Zone - YouTube )〕 and investigated whether or not these planets could still be habitable and how their spectra would look like if they were water worlds.〔(【引用サイトリンク】title=Two Water Worlds for the Price of One | www.cfa.harvard.edu/ )〕 She served four years on the Executive Council of NASA's Exoplanet Exploration Program Analysis Group (Exo-PAG) 〔http://exep.jpl.nasa.gov/exopag/ Exo-PAG〕 and is part of the Transiting Exoplanet Survey Satellite (TESS) 〔http://space.mit.edu/TESS/TESS/TESS_Overview.html TESS〕 and FGS/NIRISS〔http://jwst.nasa.gov/fgs.html FGS/NIRISS〕 science team. Kaltenegger is the founder of the Carl Sagan Institute at Cornell University and she is its current Director. 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「Lisa Kaltenegger」の詳細全文を読む スポンサード リンク
