On the Formation of the Homunculus Nebula, Skirt, and the Spin Evolution of η-Carinae    [PDF]

Tomer Shacham, Nir J. Shaviv

We model the dynamics of continuum driven winds, and show that the skirt and twin lobe structure are a generic property of critically rotating super-Eddington stars. Moreover, we show that if \eta-Carinae began its life with a high enough angular momentum, the present day wind is sufficiently concentrated towards the poles to have driven the star towards critical rotation.
