Supernovas are extremely powerful explosions of radiation. A supernova can give off as much energy as a Sun can within its whole life. A star will release most of its material when it undergoes this type of explosion. The explosion of a supernova can also help in creating new stars.
There are two types of ways a Supernova can be triggered. The first trigger is the result of a white dwarf accumulating matter from a companion. This causes the dwarf to reach a core temperature too high to survive which in turn makes an explosion. The second trigger is when a star’s nuclear fuel is diminishing and can no longer support the release of nuclear energy. If the star’s core is large enough it will breakdown and become a supernova. Most observations of a supernova are made through spectral lines. Classification agrees with the physical classification, because large stars are made of mostly hydrogen, while white dwarf stars are plain. White dwarfs have a bare surrounding because the original star’s explosion was so great that the winds pushed the hydrogen away.
A star will blow up with the help of gravitational collapses. When a star explodes from nuclear fusion it is because so much mass has built up within its core and it cannot hold the weight. Neutrons are the only things in nature that can stop a core implosion. When a white dwarf suffers a supernova, the energy comes from the runaway fusion of carbon and oxygen in the core.
After a supernova, the core is likely to travel someplace else within space. When the core is less size than about 5 solar masses, the neutrons will halt the collapse of the star. This will create a Neutron Star. Neutron stars are observed as pulsars or X-ray binaries. When the core is very large, nothing that has been discovered in the universe is able to stop the collapse. The core will completely fall into itself, this in turn creates a black hole, an object so powerful that even light cannot escape its gravitational pull.
After an explosion of a supernova, the star will give off visible light curves. Light curves are visual light and energy mechanism that differ in shape and amplitude. Light curves are powered by the after effect of the explosion and are driven by radioactive decay.
The earliest supernova was first discovered by the Chinese in 185 AD. Tycho Brahe was the second in discovering a supernova during the 1600’s. Since the development of the telescope, supernova research has now extended to more galaxies. S Andromeda in the Andromeda galaxy was discovered in 1885. During the twentieth century, scientist devoted more research towards supernovas because they offer many important facts about cosmological distances. American astronomers Rudolph Minkowski and Fritz Zwicky created the modern supernova classification scheme in 1941. During the 1960’s, astronomers discovered that supernovas can be used as standard candles of astronomical distances.
Supernova searches fall within two categories, nearby events or...
