The Egg Nebula has been regarded as the archetype of bipolar proto-planetarynebulae, yet we lack a coherent model that can explain the morphology andkinematics of the nebular and dusty components observed at high-spatial andspectral resolution. Here, we report on two sets of observations obtained withthe Keck Adaptive Optics Laser Guide Star: H to M-band NIRC2 imaging, andnarrow bandpath K-band OSIRIS 3-D imaging-spectroscopy (through the H22.121micron emission line). While the central star or engine remainsun-detected at all bands, we clearly resolve the dusty components in thecentral region and confirm that peak A is not a companion star. Thespatially-resolved spectral analysis provide kinematic information of the H_2emission regions in the eastern and central parts of the nebula and showprojected velocities for the H_2 emission higher than 100 km/s. We discussthese observations against a possible formation scenario for the nebularcomponents.
