    Current Projects

    Observational studies of Eta Carinae and the Homunculus coupled with modeling the massive binary winds and modeling the massive ejecta.

    Ongoing observations with HST, CHANDRA, Herschel, ESO's VLT and other facilities. Several collaborations leading to modeling which includes 3D wind-wind interaction studies with smoothed particle hydrodynamics, radiation transfer; atomic, molecular and dust evolution of the expanding Homunculus and Little Homunculus.
