A highly eccentric spectroscopic binary star: HD 5624
© 2019, Astronomical Institute, Slovak Academy of Sciences. In this study, we present an orbital solution for precise radial velocity (PRV) measurements of HD 5624. We obtained high resolution spectroscopic data using the Coude Echelle Spectrograph (CES) equipped with an iodine (I2) absorption cell to the 1.5 m RTT150 telescope at TÜBITAK National Observatory (TUG) and performed a spectroscopic analysis to obtain orbital parameters. The best fit Keplerian orbit was obtained with an eccentricity of e = 0:64, the mass of the companion is less than 0:5M⊙ and a period of P = 2392 days.
