Scientific paper

Radial velocities and line profiles of KP Aql (F0+F0) are analyzed, and the results are combined with those of the light-curve analysis of Ibanoglu and Gülmen to yield absolute properties of this main-sequence binary. Comparison of the properties of these stars with theoretical models of stellar evolution indicates an age of approximately 8×108yr.
