Scientific paper

High spectral and high spatial resolutions are combined in HST/STIS to reveal the neutral and ionic material in the Homunculus, ejecta of Eta Carinae. The Hubble Space Telescope`s (HST) high spatial resolution combined with the spectral resolution of Space Telescope Imaging Spectrograph (STIS) is revealing many hidden answers to questions about the character of η Car. We are examining spatially-resolved spectra recorded from 1998.0 to 2004.3 that show major changes in the stellar and nebular spectra, tracking the 2024-day period first noted in the He I λ10830 stellar line profile.
