X-Ray Observations

X-Ray Light Curve data collected and analyzed by Michael Corcoran et al

Colliding Wind Structure

Model simulated by Tom Madura

Slow, Dense Wind from Primary

Fast, less dense Wind from Companion

High temperatures resulting from Wind-Wind Collision

X-Ray Periodic Deep Minimum

X-Ray Light Curve data collected and analyzed by Michael Corcoran et al

Deep minimum

Binarity

Primary Star

~90 Solar Masses

Companion Star

~40 Solar Masses

X-Ray Flux

Model simulated by Tom Madura

Cooler temperatures while companion is within wind-radius of primary
