Abstract

Given the brightness, the V822 Aql multiple star system is photometric and spectroscopically neglected. Inthis study high-resolution echelle spectra of the system were obtained and were used to calculate the mass ratio of thesystem by determining the individual lines of the components for the first time. According to this, the close binaryconsists of two components revolving in a circular orbit with velocity semiamplitudes of $K_1$ = 45.5 ± 0.8 km/s and $K_2$= 204.9 ± 0.9 km/s (q = 0.22 ± 0.01), respectively. In addition, the orbital period analysis showed a highly eccentricorbit for the close binary together with a third body moving in a 49-year orbit. The high mass function is evidence forthe binary nature of the third body.
