What cataclysmic event is associated with the death of a star?
Nova and Supernova explosions. Which happens depends on the type and size of the star.A Nova explosion is a thermonuclear explosion occurring everywhere on the surface of an old star, in some situations multiple Nova explosions can happen over time on the same star if additional hydrogen is captured by the star.A Supernova explosion happens only in very high mass stars that have completely consumed all the fusion fuels in their core (which now consists of a plasma of the elements nickle and iron) and the core thus burns out. Without the heat of fusion to support the outer portions of the stat, it collapses. The end result of the collapse is a "rebound explosion" that blows the star apart and leaves one of two types of stellar remnants, depending on the mass of the star: a neutron star (a compact object composed of only neutrons) or a blackhole (a deep gravitational well into which all the mass of the star disappeared).
What is a sentence using explosion?
There was a explosion over there. An explosion of fire lept from her eyes as he told her that he had killed her dog.
What happens to a massive star when its fusion period is over?
Once a star's nuclear fusion has ended, it will collapse inside its core and become what is known as a white dwarf. Its outer layers will shoot out into the universe as planet nebula. If they are very large, stars will explode into a Supernova and their core will collapse into a black hole.
Why are pulsars hot?
Pulsars and neutron stars are hot because of all the residual heat left over in the core of the original star.
What event occurs at the end of the protostar stage of a star's life?
red dwarf
How long does a supernova explode?
The initial explosion is over in seconds
A what is produced when the outer core of a star explodes after the core collapses?
The process of the stellar explosion is called a "nova", or if powerful enough, a "supernova". The outer layers of gas are blown away into space, and this shell of fleeing gas is sometimes called a "supernova remnant", or more generally, a "nebula". For example, the Crab Nebula is the gas cloud left over after a supernova explosion which was brilliantly visible here on Earth in the year 1054.
What two things can be left over from a nova?
The two main items left over from a nova explosion would be the nova core and the nova remnants.
What does a massive supernova become?
If enough mass is left over after the supernova explosion, i.e. after material is blown off into space, the star will become a black hole. Less massive stars will become neutron stars. A neutron star can convert to a black hole later, if enough matter falls into it.
What is a guest star was that seen exploding over China in the year 1054?
A "guest" star is the name for the original star, before it exploded as a Supernova. Because the Supernova is the explosion and has no real physical relation to the Star, it is termed "guest" star.
What type of objects do stars end their life as?
They will end up as neutron stars or even black holes. Usually they will first explode as a supernova (of type1a).
When does a type 2 supernova begin to explode?
A massive red supergiant star will eventually explode as Type II supernova. That happens when the high mass star has run out of its nuclear "fuel". A series of nuclear fusion reactions finally ends at the nucleus of iron. A massive core of iron remains and iron can't be used to produce energy by nuclear fusion. The core collapses under gravity and the energy released throws the outer layers of the star into space in a supernova explosion. This is a Type II supernova. Sometimes it's referred to as a "core collapse" supernova, for obvious reasons. A bit more detail, if needed: A "high mass star" in this context is one with a mass of at least 8 times the mass the Sun. They develop into red supergiant stars. The mass of the iron core needs to be over the "Chandrasekhar mass" of about 1.4 times the Sun's mass. A core of that mass is unable to resist gravitational collapse. Depending on the mass of the iron core, collapse may stop at a "neutron star". Otherwise there is a complete collapse to a "black hole". See "Sources and related links", below.
How did the supernova come about?
Well in space there are billions of stars. Stars are like humans they are born, they live for a while and eventually die out. When a star reaches the end of its life it starts to produce elements in its core such as helium and other elements but when it produces IRON it has signed its death certificate, after just a few seconds after the star has produced iron it has a supernova. A supernova is the single most destructive force known to man. A supernova will destroy anything in its path. When the supernova is over all that is left is a white dwarf which is so dense that if you was to drop a sugar cube on its surface it would sink into its core thousands of miles deep.

What effect may a supernova have in a star?
Much, if not all of the material that makes up the star is expelled at extremely high speeds (up to 30,000 Km/s). The shockwave from this explosion destroys any planets or other stellar bodies within its region of influence. The shockwave also pushes all the gas and dust surrounding the star into a vast, roughly sphereical cloud, for example, 'Kepler's supernova remnant sn 1604'. This accumulation of gas and dust can can result in the growth of new stars as the gas and dust clumps together. The expelled material contains many higher mass elements such as nickel, cobalt and silicon and the material is the main source of elements heavier than oxygen which is the 8th element out of over 100 in the periodic table.
What would a supernova look from earth?
Nobody really knows. However we do know that is a spherical object - not an oblate spheroid - about the size of Manhattan (about 12km in diameter) with a very smooth surface. Smoother than anything on Earth. A young one will be very hot, and it will have a massive gravitation density. See related questions.
Conclusion of the canis major?
When the canis majoris explodes, it will create a supernova of over 30000 degrees. A supernova is a huge explosion of fire. After the supernova, a black hole will form. Black holes form when a star explodes. But it cant just be a star. It has to be a star 10x greater then our sun. The canis majoris is way bigger then just 10x. So when it explodes it will create a black hole much bigger then normal size.
