Revealing the true nature of the multiple system V822 Aql

Yıl 2018, Cilt 42, Sayı 3, 312 - 320, 01.06.2018

  Given the brightness, the V822 Aql multiple star system is photometric and spectroscopically neglected. In this study high-resolution echelle spectra of the system were obtained and were used to calculate the mass ratio of the system by determining the individual lines of the components for the first time. According to this, the close binary consists of two components revolving in a circular orbit with velocity semiamplitudes of K1 = 45.5 ± 0.8 km/s and K2 = 204.9 ± 0.9 km/s (q = 0.22 ± 0.01), respectively. In addition, the orbital period analysis showed a highly eccentric orbit for the close binary together with a third body moving in a 49-year orbit. The high mass function is evidence for the binary nature of the third body.
