The Probing Lensing Anomalies NETwork (PLANET) collaboration coordinates a network of telescopes to rapidly sample photometric measurements of the magnification of stars in the galactic bulge undergoing gravitational microlensing by intervening foreground stars (or other compact massive objects). This network consists of five 1m-class optical telescopes distributed in longitude around the southern hemisphere in order to perform quasi-continuous round-the-clock precision monitoring. On a target-of-opportunity basis, less frequent spectroscopic measurements complement the rapid photometry for selected prime targets. Since 2005, PLANET performs a common microlensing campaign with RoboNet-1.0, a network of UK-operated 2.0m robotic telescopes. In January 2009, PLANET has merged with the MicroFUN collaboration.〔(Former PLANET homepage )〕 ==Telescopes== For the 2006 observing season, the telescopes involved were (apart from the RoboNet telescopes): * Danish 1.54m telescope at ESO, La Silla, Chile () * 1.0 meter telescope at Canopus Observatory of the University of Tasmania, Australia () * 0.6 meter telescope at the Perth Observatory * South African Astronomical Observatory 1.0 meter telescope at Sutherland, South Africa () * Rockefeller 1.52 meter telescope at Boyden Observatory (Bloemfontein), South Africa () 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「Probing Lensing Anomalies Network」の詳細全文を読む スポンサード リンク
