Özet

The absolute dimensions of the components of the eccentric eclipsing binary KL CMa have been determined. The solution of light and radial velocity curves of high (Delta lambda = 0.14 angstrom) and intermediate (Delta lambda = 1.1 angstrom) resolution spectra yielded masses M-1 = 3.55 +/- 0.27 M-circle dot, M-2 = 2.95 +/- 0.24 M-circle dot and radii R-1 = 2.37 +/- 0.09 R-circle dot, R-2 = 1.70 +/- 0.1 R-circle dot for primary and secondary components, respectively. The system consists of two late B-type components at a distance of 220 +/- 20 pc for an estimated reddening of E(B - V) = 0.127.
