Sagiv Shiber (a master student), Ron Schreier, and I argue that magnetic fields amplified within a very high accretion-rate disk around main sequence stars can lead to the formation of massive bipolar outflows that can remove most of the disk’s mass and energy. Such energetic outflows can account for the powering of some eruptive objects, such as merging main sequence stars, major eruptions of luminous blue variables, such as the Great Eruption of Eta Carinae, and other Intermediate Luminosity Optical Transients (ILOTs: see the ILOT site). Such powerful outflows can also supply the extra energy required in the common envelope process and in the grazing envelope evolution of binary systems where the companion is a main sequence star.
