A Summer with Eta Carinae
ABOUT ME
Background InformationAbout Eta Carinae
The Night Sky – Southern Hemisphere
Carina Nebula
Eta Carinae
Eta Carinae
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
X-Ray Periodic Deep Minimum
X-Ray Light Curve data collected and analyzed by Michael Corcoran et al
