Supernova remnants differ from star forming regions because, although there is ionized hydrogen in both, supernova remnants: contain no ionizing stars A recurrent nova could eventually build up to a: E) contain no ionizing stars. sean_macbride7. a star showing a sudden large increase in brightness and then slowly returning to its original state over a few months.Carbon detonation is the violent reignition of thermonuclear fusion in a white dwarf, which produces a Type Ia supernovaStellar nucleosynthesis is the process by which the natural abundances of the chemical elements within stars change due to nuclear fusion reactions in the cores and their overlying mantles. Type 1 occurs among old stars of small mass, probably white dwarfs, while type 2 occurs among very young stars of large mass. Types of supernova remnant. In such a system one of the stars is a white dwarf, a small, dense star near the end of its nuclear burning phase. The last know Supernova Kelper's Supernova (also called SN 1604) happened in April, 2011, this Supernova was first observed by Johnannes Kelper on October 17, 1601!In 1054, Chinese astronomers observed the "guest star" that created the Crab nebula. B) are much bigger than star forming regions. There are three types of supernova remnant: Shell-like, such as Cassiopeia A; Composite, in which a shell contains a central pulsar wind nebula, such as G11.2-0.3 or G21.5-0.9. A supernova remnant (SNR) is the structure resulting from the explosion of a star in a supernova. We have recently found that anything with enough gravity can collapse in on it self and become a Black Hole, so even you or I could.If you were in a Supernova you would see many different colors flying everywhere, this is because the Star is releasing gases of many types. You would see the stars and planets around it (if it has any) be incinerated and engulfed!The birth a a star is much like a Supernova, but the star is being formed not created, if you were watching the birth of a star it would be much similar, only the gas would being going in not out, the gas will then compress and a star will be born.A Supernova happens about once every hundred years in the Milky Way, and if you were looking at the right time on the right day you would a big flash of light for sometimes (Not usually this one was just so far away it took awhile for the light to reach us, usually only a few hours) a hundreds of years, as the star is destroyed. The rebound causes matter to be ejected in a type 2 Supernova explosion. Its neutrino emissions could also be studied.In January 2008 astronomers witnessed the birth of a Supernova.
It quickly became an object of intense study by all the means available to modern astronomy. Supernova remnants play a vital role in the evolution of galaxies. Log in Sign up.
