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. 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.
