Özet
In this study, I present the first analysis of spectroscopic observations of southern detached eclipsing binary star HD 53570. The spectroscopic observations of HD 53570 was made at the Sutherland Station of the South African Astronomical Observatory (SAAO) in 2013 and 2014. Radial velocities (RVs) of the components of HD 53570 were determined by cross-correlation technique (CCT). The H beta (4861.36 angstrom) lines of the components of HD 53570 were chosen as the most suitable lines for reliable RV measurements. The resulting orbital elements of HD 53570 is calculated as, a(1) sin i = 0.0258 +/- 0.0005 AU, a(2) sin i = 0.0228 +/- 0.0005 AU, M-1 sin(3)i = 1.035 +/- 0.046 M-circle dot and M-2 sin(3)i = 1.167 +/- 0.050 M-circle dot. The radial velocity models of HD 53570 give the close binaries mass ratio as 1.13 +/- 0.07.
