Abstract

High angular resolution adaptive optics data have been obtained on (eta) Carinae and Homunculus nebula, with the ESO ADONIS system. In the broad band filters, J, H and K, the central source, (eta) Car was allowed to saturate in order to maximize the signal for the extended Homunculus nebula. Unsaturated images were also obtained in a narrow continuum filter. The purpose of these observations was to explore the 3D shape of the Homunculus through high spatial resolution imaging polarimetry. The polarization of resolved knots and filaments, will allow their position along the line of sight to be determined when combined with scattering models. Here the observational details, data reduction and preliminary results are presented.
