Eta Carinae: The 2003.5 Observing Campaign: Papers and Presentations

"They finally came together in a fearful last death grip, in the midst of thick clouds and tempestuous elements; they fell to the ground with such force that they shook the whole world."

Relation of the X-ray Minima to the Historical Visual Lightcurve

In 2003.5 Eta Carinae, one of the most luminous and massive stars in the Universe, is expected to undergo an X-ray eclipse. This X-ray eclipse is believed to occur every 5.52 years and is apparently correlated with the 5.52 year fading of high excitation lines (like He II 10830 Å published by Augusto Damineli). The X-ray emission is thought to arise at a shock front produced as the wind from Eta Car slams into the wind from a less massive (but hotter) companion star. The eclipse may be produced as the shock front around the companion moves behind the thick wind of Eta Car. The upcoming eclipse marks only the 3rd time the X-ray eclipse has been seen (the first time was a fortuitous observation with ROSAT), and we hope will mark the first time the event is observed by the full complement of ground-based and space based instrumentation. This page summarizes some of the planned observations, and results as they become available.
