Imposter Supernova

What is it?
An Imposter, is one who poses as someone or something that they are not. Perhaps like a mocking bird who mimics the voice of another bird in order to draw in prey for the hunt. This can happen in space as well; more specifically with supernovae. This fake is known as a supernova imposter. Supernova imposters are interstellar explosions that at first are thought and seen to be supernovae, alas this explosion is not the result of the death of the host star. Therefore instead of being classified as supernova, which would require a stars death, this explosion is called a Supernova Imposter. They are also known as Type V Supernovae, Extra-Powerful Novae, Eta Carinae analogs and giant eruptions of luminous blue variables or LBV. Some discovered Supernova Imposters are The Great Eruption of Eta Carinae, SN 1954J, SN 2008S and NGC 6946.
