| Abstract: |
We report on the recent discovery of two new massive binary systems: WR20a and CygOB2#8A. For both systems, we briefly present the orbital solutions and we discuss the strong phase-locked line profile variability of the Hα and HeII λ 4686 lines for WR20a, and the HeII λ 4686 line in the case of CygOB2#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. |
