Rapidly accelerating clumps in the winds of the very hot WNE Stars

Rapidly accelerating clumps in the winds of the very hot WNE Stars

We study the time variability of emission lines in three WNE stars : WR 2 (WN2), WR 3 (WN3ha) and WR152 (WN3). While WR 2 shows no variability above the noise level, the other stars do show variation, which are like other WR stars in WR 152 but very fast in WR 3. From these motions, we deduce a valu...
