Discoveries

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.^[8] The exoplanet has a minimum mass of 1.4 Jupiter masses, and rotates its parent star from about 1.05 AU (156,000,000 km (97,000,000 mi)) 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 (CES) installed on the 1.5-meter Russian-Turkish Telescope (RTT150). Follow-up observations at the Okayama Astrophysical Observatory (OAO) in Japan and the Ankara University Kreiken Observatory (AUKR) confirmed the discovery, which was made public on August 6, 2017.^[9]
