Özet
High resolution (R=45033) Coude - Echelle spectra of IX Per has been obtained at TUBITAK National Observatory (TUG) of Turkey. IX Per has been known to be a single lined (SBI) spectroscopic binary having chromospheric activity. However, analyzed spectra of IX Per by KOREL disentangling method indicated that the system is a double lined (SB2) spectroscopic binary. Weaker lines from the secondary arc discovered on the decomposed spectra. A preliminary orbit indicates that the mass ratio of the system is 0.64. The light contribution of the secondary is tip to 10% in investigated spectral region. Circular orbit is sufficient to explain radial velocity variations.
