Spectroscopic observations of eccentric eclipsing binary systems
Abstract
Eccentric eclipsing binaries (EEBs) are detached binary stars. Many EEBs show apsidal motion. EEB fundamental physical parameters allow us to test stellar evolution models and to estimate the internal stellar structure constants through apsidal motion analysis. We started a programme to study EEBs at the UBT60 telescope of Akdeniz University located at TÜBİTAK National Observatory. In this paper, we present spectroscopic orbital parameters of some selected EEBs.
