Abstract

Hubble Space Telescope observations and interferometric measurements provide unique insights into the small-scale structure of η Car’s circumstellar ejecta and its extreme, optically thick, aspherical stellar wind. We discuss speckle interferometric imaging and HST images of η Car’s ejecta in the inner 1 arcsec. We also review the first infrared long-baseline spectro-interferometry with high spatial resolution of 5 mas and high spectral resolution. Infrared interferometry allows us, for the first time, to study the strong wavelength dependence of η Car’s non-spherical wind structure within emission lines.
