Five KFU employees have been involved in the project - Ilfan Bikmaev, Eldar Irtuganov, Roman Zhuchkov, Almaz Galeev, and Sergey Melnikov.
Professor Bikmaev, Chair of the Department of Astronomy and Space Geodesy, commented on the news, "In the course of our 10-year work of searching for exoplanets around red giants with a Russian-Turkish 1.5-meter telescope (RTT-150) at Tubitak National Observatory and a 1.88-meter telescope in Japan we have made hundreds of measurements of radial velocities with the use of iodine absorption cells.
The chosen group includes 50 cold red giants within several hundred light years from us. The analysis of changes in radial velocities of HD208897 showed that in the vicinity of approximately 1 astronomical unit of it there is an exoplanet with a 1.4 Jupiter's mass and a period of 353 days".
In the last 20 years several thousand exoplanets have been found orbiting solar-type stars, but only about a hundred around giant stars. Most of them are 10 to 20 times heavier than Jupiter, and only about 15 planets are close to Jupiter in mass. This is the first time in Russian astronomy when a planet was discovered with spectroscopic methods. A high-resolution echelle spectrometer, produced with participation from Tatarstan Academy of Sciences, and a Japanese iodine cell were used for the project.
Dr. Bikmaev said that Kazanites plan to continue efforts in planet search together with their co-authors.

One of NASA's proposed missions, known as the Fast INfrared Exoplanet Spectroscopy Survey Explorer (FINESSE) could greatly improve our understanding of extrasolar worlds. If selected for development, the spacecraft will investigate at least 500 exoplanet atmospheres, providing detailed information about climate processes on distant alien planets. FINESSE has been recently chosen by NASA fo ... read more
