When a main-sequence star exhausts its hydrogen fuel in the core, nuclear fusion ceases, causing the core to contract under gravity and heat up. As the core temperature rises, it eventually becomes hot enough to fuse helium into heavier elements, leading the star to expand into a red giant. This phase may result in the outer layers being ejected, forming a planetary nebula, while the core can either become a white dwarf or, in more massive stars, undergo a supernova explosion, leaving behind a neutron star or black hole.
What else can I help you with?
What happens when a neutron star runs out of fuel?
Neutron stars do not have fuel. A neutron star is a remnant of a star that has already died.
What happens to a large star when it runs out of fuel?
When a large star runs out of fuel, it undergoes a supernova explosion, where the core collapses and releases a huge amount of energy. The outer layers are expelled into space, forming a nebula, while the core either forms a neutron star or a black hole, depending on its mass.
What makes a star lose its shine?
A star can lose its shine as it runs out of fuel and expands into a red giant, or collapses into a white dwarf, neutron star, or black hole. This process is part of the star's natural life cycle and can result in changes in its brightness and appearance.
What are two types of stars that can form when a star runs out of fuel?
When a Star runs out of fuel, it will expand into what is known as a "Red Giant". Massive stars will become "Red Supergiants". This phase will last until the star exhausts its remaining fuel. At this point, the pressure of the nuclear reaction is not strong enough to equalize the force of gravity and the star will collapse. Go to related link to read more about Stars... ;)
What happens when a high mass star exhausts its fuel?
It will probably explode as a supernova, leaving either a neutron star or black hole.
What happens when a neutron star runs out of fuel?
Neutron stars do not have fuel. A neutron star is a remnant of a star that has already died.
How the black hole make?
A black hole is the result of the gravitational collapse of a massive star. This happens when the star runs out of fuel.
What does a star turn into after it runs out of fuel?
a dwarf star
What happens to a large star when it runs out of fuel?
When a large star runs out of fuel, it undergoes a supernova explosion, where the core collapses and releases a huge amount of energy. The outer layers are expelled into space, forming a nebula, while the core either forms a neutron star or a black hole, depending on its mass.
When a neutron star runs out of fuel what does it become?
A neutron star is already the remains of a massive star that has run out of fuel.
The death of a star occurs when?
When the star runs out of fuel. Most stars burn (fuse, actually) hydrogen. When this runs out, what happens next depends on the mass of the star... heavier stars can fuse heavier elements for a short time, but lower mass stars simply collapse into white dwarfs.
The death of a star occurs when its?
The death of a star occurs when its nuclear fusion processes can no longer sustain the outward pressure generated by the energy produced in its core. This can lead to the star collapsing under its own gravity, culminating in a supernova explosion or the formation of a white dwarf, neutron star, or black hole depending on its mass.
What begins the death of a star?
Usually the fact that the star runs out of fuel.
What happens to a star when it has used up all its fuel?
It collapses.
What happens to a massive star after it runs out of fuel?
When a massive star runs out of fuel, it undergoes a supernova explosion. The core of the star collapses under gravity, leading to the formation of a neutron star or black hole, depending on the final mass of the star. The outer layers of the star are expelled into space, enriching the surrounding environment with heavy elements.
Which star expands due to fusion?
As a star ages and runs out of fuel in its core, it can expand in size as it transitions into a red giant. During this phase, fusion reactions occur in the outer layers of the star, causing it to expand and cool. This expansion happens when the star exhausts its hydrogen fuel and begins fusing helium in its core.
When a star runs out if hydrogen what does it use as fuel source?
helium
