X-Ray Evidence for Flare Density Variations and Continual Chromospheric Evaporation in Proxima Centauri
Manuel Guedel, Marc Audard, Stephen L. Skinner +1
Using the XMM-Newton X-ray observatory to monitor the nearest star to the Sun, Proxima Centauri, we recorded the weakest X-ray flares on a magnetically active star ever observed. C…
XMM-Newton and VLA Observations of the Variable Wolf-Rayet Star EZ CMa: Evidence for a Close Companion?
S. L. Skinner, S. A. Zhekov, M. Guedel +1
We present new X-ray and radio observations of the WR star EZ CMa (HD 50896) obtained with XMM-Newton and the VLA. This WN4 star shows optical/UV variability at a period of 3.76 d…
High-Resolution X-ray Imaging of the Colliding Wind Shock in WR147
J. M. Pittard, I. R. Stevens, P. M. Williams +4
We analyze new high-resolution Chandra X-ray images of the Wolf-Rayet binary system WR147. This system contains a WN8 star with an early-type companion located 0.6'' to its north,…
XMM-Newton Detection of Hard X-ray Emission in the Nitrogen-Type Wolf-Rayet Star WR110
S. L. Skinner, S. A. Zhekov, M. Guedel +1
We have used the excellent sensitivity of XMM-Newton to obtain the first high-quality X-ray spectrum of a Wolf-Rayet (WR) star which is not known to be a member of a binary system.…
