superluminous supernova

(SLSN, hypernova, superluminous SN)
(stellar explosion larger than a supernova)

A superluminous supernova (SLSN or superluminous SN or hypernova) is a stellar explosion more energetic than a normal supernova, i.e., they can be classified as very large supernovae. Most are Type Ic or Type IIn supernovae, termed Type I SLSN (or SLSN-I), Type II SLSN (or SLSN-II), They are theorized to be core collapse supernovae, but some don't fit that pattern. They are also thought to be the origin of long-duration gamma-ray bursts (LGRBs).

A third type called SLSN-R (for "radioactive") apparently with electromagnetic radiation produced by a radioactive nickel isotope.

Among theories explaining their mechanisms:

(stars,event type,transient type)
