Abstract
We present here 2D hydrodynamical simulations of the eruptive events of the 1840s and the 1890s eruptions suffered by the massive star η Car. We assume a colliding wind scenario to explain the shape and kinematics of the bipolar nebulae formed from these events. We also find the formation of some tenuous, equatorial, high-speed features that seem to be related to the observed equatorial skirt of η Car.
