Young eccentric binary KL CMa revisited in the light of spectroscopy

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.
