Resumen:
We present a radial velocity study of LSS 1964 (= WR 29) based on digital spectral images obtained with the 2.15-m telescope at CASLEO, San Juan, Argentina, between 1997 and 2000. We find this star to be a double-lined WN + O binary with a period of 3.16415 days. The WN component appears to be more massive than the O type component. Niv absorption at ~ lambda 5203 Å is found to belong to the WN7 star.
