What type of supernova happens when a star exceeds 8 solar masses and explode?

What type of supernova happens when a star exceeds 8 solar masses and explode?

Type II supernovae
Type II supernovae For a star to explode as a Type II supernova, it must be at several times more massive than the sun (estimates run from eight to 15 solar masses). Like the sun, it will eventually run out of hydrogen and then helium fuel at its core. However, it will have enough mass and pressure to fuse carbon.

What is the final state of the star if its initial mass is less than of equal to 1.44 times the mass of the Sun *?

Even for these more massive stars, however, if the residual mass in the core is less than 1.4 solar masses (the Chandrasekhar limit), the stellar remnant will become a white dwarf. The matter in such a dwarf becomes a degenerate gas, wherein the electrons are all stripped from their parent atoms.

What happens if the leftover core of a supernova is more massive than 3 solar masses?

A massive star will undergo a supernova explosion. If the remnant of the explosion is 1.4 to about 3 times as massive as our Sun, it will become a neutron star. The core of a massive star that has more than roughly 3 times the mass of our Sun after the explosion will do something quite different.

What happens to the core of a super massive star after it became a supernova at the end of its life?

(2) A massive star ends with a violent explosion called a supernova. In the absence of effective pressure support, the iron core collapses in less than a second. When the core reaches the density of an atomic nucleus (an amazing 400 million tons per cubic centimeter), it resists further compression and bounces back.

What happens during a Type 2 supernova?

A Type II supernova (plural: supernovae or supernovas) results from the rapid collapse and violent explosion of a massive star. The star fuses increasingly higher mass elements, starting with hydrogen and then helium, progressing up through the periodic table until a core of iron and nickel is produced.

What happens after a supernova dies?

The remnants of the stellar core which are left after the supernovae explosion will follow one of two paths: neutron star or black hole.

What happens to a star at the end?

The events at the end of a star’s life depend on its mass. Really massive stars use up their hydrogen fuel quickly, but are hot enough to fuse heavier elements such as helium and carbon. Once there is no fuel left, the star collapses and the outer layers explode as a ‘supernova’.

What happens to stars that are 8 times the Sun’s mass?

If your star is more than 8 times the mass of the Sun, it will not only fuse hydrogen into helium and helium into carbon, but will initiate carbon fusion later on, leading to oxygen fusion, silicon fusion, and eventually, a spectacular death by supernova.

In which stage do massive star explode and release large amount of energy?

supernova
A supernova (/ˌsuːpərˈnoʊvə/ plural: supernovae /ˌsuːpərˈnoʊviː/ or supernovas, abbreviations: SN and SNe) is a powerful and luminous stellar explosion. This transient astronomical event occurs during the last evolutionary stages of a massive star or when a white dwarf is triggered into runaway nuclear fusion.
