[8.06] Changes in the Nebula Around Eta Carinae

M.D. Koppelman (University of Minnesota), E. Reilly (University of Wisconsin), K.D. Davidson, J.C. Martin (University of Minnesota)

Eta Carinae has proven to be a dynamic object on time scales of months and years. Using 6 years of data from the Hubble Space Telescope acquisition camera (ACQ) we investigated changes in the nebula around Eta Carinae. The images were deconvolved using the Lucy-Richardson algorithm and the changes analyzed with several photometric and cross-correlation techniques. We find that there are measurable changes during this relatively short baseline which may result from the expansion of the nebula or changes in its illumination or both.
