Abstract
Eta Carinae, with its historical ejection events of the 19th century and propinquity, provides an excellent test bed for understanding how the most massive stars transition from hydrogen burning to the presupernova stage.
The next X-ray and visible/UV spectroscopic event, associated with the binary periastron, is predicted to be January 11, 2009 +/- 2 days. Observations are being prepared and proposed to test models of the binary system and response by the ejecta to changes in the photo-excitation. This poster will describe current and developing models and observations that are planned to test and further enhance these models. We solicit additional observational and modeling efforts.
We acknowledge the resources of the many observatories supporting this project.
