- or it will explode and swallow or like … melt the inner planets and it will lose its gravitational pull and the planets remaining will float off in space alone and the star would turn into a white dwarf then into a black hole =) Edit: A massive star becomes a Type II Supernova.

What are Stars and How Long do they Live? A neutron star, like a white dwarf or black hole, is actually not a star but a stellar remnant. When a massive star reaches the end of its life it undergoes a supernova explosion, leaving behind its incredibly dense core. A soup-can full of neutron star material would have about the same mass as our Moon.

- A neutron star is a type of compact star that can result from the gravitational collapse of a massive star after a supernova. Neutron stars are the densest and smallest stars known to exist in the universe; with a radius of only about 12–13 km (7 mi), they can have a mass of about twice that of the Sun.ndeed, the discovery of pulsars in 1967 first suggested that neutron stars exist. Gamma-ray bursts may be produced from rapidly rotating, high-mass stars that collapse to form a neutron star, or from the merger of binary neutron stars.

nova The material, mostly hydrogen and helium, is attracted by the white dwarf's gravity and accumulates under growing pressure and heat until nuclear fusion is ignited. Unlike a supernova, a nova is not blown apart by the explosion and gradually returns to its original brightness over a period of weeks to years.

- A neutron star is formed by the gravitational collapse of a massive star during a Supernova event. The density of the star is maintained by the total mass of the star. If a … small piece of the star broke free, which of course would be highly unlikely due to the large surface gravity.t is a big ball with a diameter of some 1.392 x 109 meters. Taking the sun away and sticking in a typical neutron st … ar would mean substituting that big ball with something only some 20 to 40 kilometers in diameter. The neutron star is miniscule compared to the sun.

- This type of supernova is caused by a white dwarf. A white dwarf is the remnant of a sun-like star at the end of its life, a body of about 1 solar mass, mainly composed of carbon and oxygen. The matter is compressed into an earth-sized object with a diameter of between 11000 and 28000 km.

General Astronomy/Print version A white dwarf is a compact star. Their matter is squashed together. Gravitation has pulled the atoms close together, and stripped off their electrons. The mass of a white dwarf's mass is similar to that of the Sun, but its volume is similar to that of the Earth.

Formation of the High Mass Elements Upon the death of a star (in a nova or a supernova) these high mass elements, along with even more massive nuclei created during the nova or supernova, were thrown out into space to eventually become incorporated into another star or celestial body.

How is the death of a very large star different from the death of a small star? A smaller star loses heat very slowly and generally loses mass and luminosity till it becomes a black dwarf-meaning, we can't see it anymore. According to the theory of degenerate pressure, it will take an infinite amount of time to disappear. ssheffield89 · 8 years ago.eport Abuse. A small star will go nova, leaving behind a small dwarf star, usually a white dwarf. A very large star will go supernova, and could possibly leave behind a neutron star or a black hole.

supernova 1. 1  the explosion of a star, possibly caused by gravitational collapse, during which the star's luminosity increases by as much as 20 magnitudes and most of the star's mass is blown away at very high velocity, sometimes leaving behind an extremely dense core. 2  the star undergoing such an explosion.

Phys 105 Astronomy Ch. 18 Study Set A neutron star has a mass limit of about 2 to 3 solar masses. If a supernovae occurs when a star is too massive to become a neutron star, the result is a black hole. Observationally, we can detect black holes through the gravitational influence on other objects and by the way they block out other objects.

Astronomy Chapter 10 The maximum mass of a white dwarf, about 1.4 solar masses. A white dwarf of greater mass cannot support itself and will collapse. A star cluster containing 100,000 to 1 million stars in a sphere about 75 ly in diameter that is generally old, metal-poor, and found in the spherical component of a galaxy.

Why do high and low mass stars evolve differently as they become red giants? That is why they are closer towards the red side of the spectrum. Eventually the fusion of heavier elements will cause the formation of iron in most stars and the fusion process can't continue. Gravity then takes over and causes the star to collapse inward causing the material to rebound into what is a type 2 supernova. The only difference really is that with smaller stars like the sun the fusion won't continue until there is iron, but rather the star will blow off outer layers since the star is not big enough and will leave behind a white dwarf.

Stars A supernova is not merely a bigger nova. In a nova, only the star's surface explodes. In a supernova, the star's core collapses and then explodes. In massive stars, a complex series of nuclear reactions leads to the production of iron in the core.

Type II supernova Type Ib and Ic supernovae are a type of core-collapse supernova for a massive star that has shed its outer envelope of hydrogen and (for Type Ic) helium. As a result, they appear to be lacking in these elements.

Betelgeuse: The Eventual Supernova Credit: ESA/Herschel/PACS/L. Betelgeuse is a star nearing the end of its life. Because it is creating heavier and heavier elements in its core that could be used for stars after it dies, a NASA story once dubbed the red giant a workaholic.

The Life of a Star Massive stars have a mass 3x times that of the Sun. Some are 50x that of the Sun. Stage 1 - Massive stars evolve in a simlar way to a small stars until it reaces its main sequence stage (see small stars, stages 1-4).The stars shine steadily until the hydrogen has fused to form helium (it takes billions of years in a small star, but only millions in a massive star).he star expands to a Red Giant, below. Stage 8 - The helium core runs out, and the outer layers drift of away from the core as a gaseous shell, this gas that surrounds the core is called a Planetary Nebula.

How Stars Work How the star dies, however, depends on what type of star it is. Stars Like the Sun. When the core runs out of hydrogen fuel, it will contract under the weight of gravity. However, some hydrogen fusion will occur in the upper layers. As the core contracts, it heats up. This heats the upper layers, causing them to expand.As the outer layers expand, the radius of the star will increase and it will become a red giant.The radius of the red giant sun will be just beyond the Earth's orbit. At some point after this, the core will become hot enough to cause the helium to fuse into carbon.ow the star dies, however, depends on what type of star it is. Stars Like the Sun.

Stars Neutron Stars If the collapsing stellar core at the center of a supernova contains between about 1.4 and 3 solar masses, the collapse continues until electrons and protons combine to form neutrons, producing a neutron star. Neutron stars are incredibly dense - similar to the density of an atomic nucleus. Because it contains so much mass packed into such a small volume, the gravitation at the surface of a neutron star is immense. Like the White Dwarf stars above, if a neutron star forms in a multiple star system it can accrete gas by stripping it off any nearby companions.

- Best Answer: The initial size of the star is what decides. A star is huge, I mean really big, and all that gravity wants to pull itself together (everything attracts). So, the star wants to collapse. But, it creates nuclear fusion, and that is the force that pushes the star out.
