| Abstract |
|---|
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
and
HeII 
4686 lines for WR 20a,
and the HeII 4686 line in the case
of Cyg OB2 #8A. In both cases, we show that the profile
variability reveals a signature of a wind interaction. The prospects
for future high-energy observations are also discussed.
