TÜBİTAK National Observatory


TÜBİTAK National Observatory is a ground-based astronomical observatory operated by the TUG Institute of the Scientific and Technological Research Council of Turkey. Established in 1991, it is located at an altitude of in Bakırtepe, around west-southwest of Antalya in southern Turkey.
There are five telescopes installed in Bakırtepe:
Scientists led by a Turkish astronomer from Ankara University discovered an exoplanet orbiting the giant star HD 208897, which is located at a distance of some 210 light years from the Earth. The exoplanet has a minimum mass of 1.4 Jupiter masses, and rotates its parent star from about 1.05 AU away in every 353 days on a nearly circular orbit. The discovery is the result of a ten-year-long research work of precise radial-velocity method carried out by using the Coude Echelle Spectrograph installed on the 1.5-meter Russian-Turkish Telescope. Follow-up observations at the Okayama Astrophysical Observatory in Japan and the Ankara University Kreiken Observatory confirmed the discovery, which was made public on August 6, 2017.
