Scientific paper

Optical spectroscopy of the early-type HD 141929 reveals this star to be a double-lined binary system. We obtained the first orbit, consisting of an eccentric solution (e = 0.393) with a period of 49.699 d and semi-amplitudes of 9.95 and 10.58 km s-1. The mass ratio reaches only 0.94 and both components have the same spectral type A0/1V, however, the secondary is rotating slower than the primary.
