The usage of the term hypernova from the late 20th century has since been refined to refer to those supernovae with unusually large kinetic energy. The first hypernova observed was SN 1998bw, with a luminosity 100 times higher than a standard Type Ib. This supernova was the first to be associated with a gamma-ray burst (GRB) and it produced a ...
Type Ia supernova; Type Ib and Ic supernovae; Type II supernova; Superluminous supernova; Pair-instability supernova; Hypernova; Supernova impostor, stellar explosions that appear similar to supernova, but do not destroy their progenitor stars Failed supernova; Luminous red nova, an explosion thought to be caused by stellar collision
The word supernova has the plural form supernovae (/-v iː /) or supernovas and is often abbreviated as SN or SNe. It is derived from the Latin word nova, meaning ' new ', which refers to what appears to be a temporary new bright star. Adding the prefix "super-" distinguishes supernovae from ordinary novae, which are far less luminous.
SN 1054 remnant (Crab Nebula)A supernova is an event in which a star destroys itself in an explosion which can briefly become as luminous as an entire galaxy.This list of supernovae of historical significance includes events that were observed prior to the development of photography, and individual events that have been the subject of a scientific paper that contributed to supernova theory.
The Type Ia supernova leaves no compact remnant, but the whole mass of the former white dwarf dissipates through space. The theory of this type of supernova is similar to that of novae, in which a white dwarf accretes matter more slowly and does not approach the Chandrasekhar limit. In the case of a nova, the infalling matter causes a hydrogen ...
The nature of ASASSN-15lh is disputed. The most popular explanations are that it is the most luminous type I supernova (hypernova) ever observed, or a tidal disruption event around a 10 8 M ☉ supermassive black hole. [5] Other hypotheses include: gravitational lensing; a quark nova inside a Wolf–Rayet star; or a rapid magnetar spindown.
A super-luminous supernova (SLSN, plural super luminous supernovae or SLSNe) is a type of stellar explosion with a luminosity 10 or more times higher than that of standard supernovae. [1] Like supernovae , SLSNe seem to be produced by several mechanisms, which is readily revealed by their light-curves and spectra .
It is from the title of this book that the modern word nova for cataclysmic variable stars is derived. [23] Multiwavelength X-ray image of the remnant of Kepler's Supernova, SN 1604.
