Colliding Winds in and around the Stellar Group IRS 13E at the Galactic Center
Q. Daniel Wang, Jun Li, Christopher M. P. Russell +1
IRS~13E is an enigmatic compact group of massive stars located in projection only 3.6 arcseconds away from Sgr A*. This group has been suggested to be bounded by an intermediate-ma…
Non-thermal X-rays from Colliding Wind Shock Acceleration in the Massive Binary Eta Carinae
Kenji Hamaguchi, Michael F. Corcoran, Julian M. Pittard +9
Cosmic-ray acceleration has been a long-standing mystery and despite more than a century of study, we still do not have a complete census of acceleration mechanisms. The collision…
Modelling the thermal X-ray emission around the Galactic centre from colliding Wolf-Rayet winds
Christopher M. P. Russell, Q. Daniel Wang, Jorge Cuadra
We compute the thermal X-ray emission from hydrodynamic simulations of the 30 Wolf-Rayet (WR) stars orbiting within a parsec of Sgr A, with the aim of interpreting the Chandra…
Discovery of Rapidly Moving Partial X-ray Absorbers within gamma Cassiopeiae
K. Hamaguchi, L. Oskinova, C. M. P. Russell +4
Gamma Cassiopeiae is an enigmatic Be star with unusually strong hard X-ray emission. The Suzaku observatory detected six rapid X-ray spectral hardening events called "softness dips…
Hydrodynamic and radiative transfer modeling of X-ray emission from colliding WR winds: WR 140 & the Galactic center
Christopher M. P. Russell, Michael F. Corcoran, Jorge Cuadra +6
Colliding Wolf-Rayet (WR) winds produce thermal X-ray emission widely observed by X-ray telescopes. In wide WR+O binaries, such as WR 140, the X-ray flux is tied to the orbital pha…
A Coordinated X-ray and Optical Campaign of the Nearby Massive Binary Orionis Aa: II. X-ray Variability
J. S. Nichols, D. P. Huenemoerder, M. F. Corcoran +18
We present time-resolved and phase-resolved variability studies of an extensive X-ray high-resolution spectral dataset of the Orionis Aa binary system. The four observations, o…
