Abstract

I will present the view that jets launched by the more compact star during the common envelope evolution (CEE) supply the extra energy that is required to unbind the envelope. I will then present the first 3D simulations of the grazing envelope evolution (GEE). Jets launched from a secondary main sequence star manage to eject the envelope without any extra energy source. Such an event can be observed as intermediate luminosity optical transient (ILOT). I call for a paradigm shift in our approach to the CEE, where in the new paradigm jets play important role in ejecting the envelope and shaping the outflow.
