摘要
We report on the recent discovery of two new massive binary systems: WR 20a and Cyg OB2#8A. For both systems, we briefly present the orbital solutions and we discuss the strong phase-locked line profile variability of the H alpha and HeII lambda 4686 lines for WR 20a, and the HeII lambda 4686 line in the case of Cyg OB2 #8A. In both cases, we show that the profile variability reveals the signature of a wind interaction. The prospects for future high-energy observations are also discussed.
