Supernova Impostors and other Gap Transients

Abstract

Besides supernovae, few astrophysical processes can release close to 10^51 erg of energy. A growing number of stellar outbursts are now recognised to have energy releases matching those of faint supernovae. These transients can be triggered by a variety of mechanisms, and their discrimination is sometimes a tricky issue.
