# Supernova Impostors and other Gap Transients

## TL;DR

This paper reviews various astrophysical transients, including supernova impostors and gap transients, focusing on their energy release mechanisms and challenges in distinguishing them from true supernovae.

## Contribution

It provides a comprehensive overview of the mechanisms behind supernova impostors and gap transients, highlighting their similarities and differences with faint supernovae.

## Key findings

- Many transients release energies comparable to faint supernovae.
- Discriminating between different types of transients is often challenging.
- Understanding these transients helps clarify stellar explosion phenomena.

## 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.
