A large cool star that forms when a star exhausts its hydrogen fuel is known as a red giant. During this phase, the star expands and cools as it begins to fuse helium and heavier elements in its core. Red giants are typically much larger than their previous main-sequence state and can eventually shed their outer layers, leading to the formation of planetary nebulae or, in the case of more massive stars, evolve into supernovae.

A large cool star formed when a star runs out of hydrogen?
red giant
What is large cool star formed when a star runs out of hydrogen?
A supergiant or red giant. They are normally around 3,500 degrees C and are very bright, near -5 on the Hertzsprung-Russell Diagram. These are the largest stars in the galaxy and universe.
Does nuclear fusion occurs as stars cool down?
The star will continue to fuse hydrogen until it runs out of resources and dies out, after which it will collapse and die.
When a low mass star first runs short of hydrogen in its core it becomes brighter because?
Low mass stars become brighter after depleting hydrogen because all of the hydrogen in the core has been fused into helium. Once this happens, hydrogen fusion begins in the outer layers, which causes more heat and light generation.
What element does a star run out of that causes them to die?
A star dies when it runs out of fuel to sustain nuclear fusion in its core. This fuel is mainly hydrogen, which gets converted into helium through nuclear fusion. Once the star runs out of hydrogen, it will expand and eventually collapse, leading to its death in a supernova explosion.

What is a large cool star form when a star runs out of hydrogen?
When a star runs out of hydrogen in its core, it starts fusing helium into heavier elements like carbon and oxygen. This process causes the outer layers of the star to expand and cool, becoming a red giant.
How is the red-giant formed?
A red giant forms when a star runs out of hydrogen fuel at its core and starts fusing hydrogen in a shell around the core the core. This causes the star to expand and cool.
Does nuclear fusion occurs as stars cool down?
The star will continue to fuse hydrogen until it runs out of resources and dies out, after which it will collapse and die.
Why does a star's hydrogen supply run out?
A star's hydrogen supply runs out because of nuclear fusion in its core. As hydrogen is fused into heavier elements like helium, the star's core temperature increases, causing it to expand and cool. Eventually, the core runs out of hydrogen to fuse, leading to the star's evolution into a different phase.
What happens to the core of a high-mass star after it runs out of hydrogen?
After a high-mass star runs out of hydrogen, the core undergoes nuclear fusion of helium into heavier elements like carbon and oxygen. This process continues until iron is formed, at which point the core collapses and triggers a supernova explosion.
What is the largest desert that runs along southwestern coast?
The Namib Desert is the large desert on Africa's southwestern coast. It is a cool coastal desert.
What is the large desert that runs along southwestern coast?
The Namib Desert is the large desert on Africa's southwestern coast. It is a cool coastal desert.
Is there a car that runs on water?
They are working on that. They have machines that can separate the hydrogen from the oxygen. An automobile can run on hydrogen.
When a star runs out if hydrogen what does it use as fuel source?
helium
How much water will a car that burns hydrogen exhaust?
if it runs on pure hydrogen then the only exhaust will be pure water vapor.
