Özet
Isochronal ages of the 32 eclipsing binary stars with eccentric orbits from the catalog of Bulut and Demircan (2007) were computed using the Y2 stellar evolution models. First, we derived the metallicity Z-values from evolutionary sequences. Then, using these metallicity in the Y2 models, a set of isochrones were computed. Lastly, the ages were found from the isochrone that was best-fitting the locations of both components. 19 of the 32 ages were calculated with a 20% accuracy. These were compared with the circularization times-scales. © 2022, Institute of Astronomy and Rozhen NAO. All rights reserved.
