Özet

We present preliminary results from the analysis of spectroscopic observations of the southern eclipsing binary star V454 Car (HIP 36682). High-resolution spectra of the system were taken at the Mt. John University Observatory in 2009, 2010, 2011, and 2014. Detailed examination of the spectra indicates that V454 Car is a triple system. Radial velocities of the components of the eclipsing pair were obtained. The orbital solution gave quite a large spectroscopic mass ratio of q(spec) = 0.93 +/- 0.05.
