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.
What fuses during the red giant phase?
During the red giant phase, hydrogen fusion occurs in the shell surrounding the helium core. The core is no longer fusing hydrogen, as it has already converted most of its hydrogen into helium. This causes the outer layers of the star to expand and cool, leading to the red giant phase.
What is an old star of average size that has begun to expand and cool as its fuel has begun to run out?
Red giant.
What element is the main fuel for red giant stars?
The main fuel for red giant stars is helium. In the core of red giant stars, hydrogen fusion has ceased, and as the star evolves, it starts fusing helium into heavier elements like carbon and oxygen. This process produces the energy that sustains the star's outer layers and causes it to expand and cool, creating a red giant.
Will your sun become a red super red giant or a red giant?
Our Sun will eventually become a red giant, not a red supergiant. As it exhausts its hydrogen fuel in about 5 billion years, it will expand and cool, turning into a red giant. A red supergiant, on the other hand, is a larger star that has significantly more mass than the Sun and undergoes a different evolutionary path.
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.

What is the causes of the end of the?
In about 5 billion years the sun will expand to a red giant and fry Mercury, Venus and earth.

What is an eight letter word that the definition is an old star of average size that has begun to expand and cool as its fuel has begun to run out?
red giant
What is an expanding star after exhausting its hydrogen fuel called?
An expanding star after exhausting its hydrogen fuel is called a red giant. This stage occurs when the core contracts and heats up, causing the outer layers of the star to expand and cool, giving it a red color.
How large will the sun be as a red giant?
When the sun becomes a red giant, it will expand to about 100 times its current size.
How long will the sun's red giant stage last for?
The sun's red giant stage will last for 1 or 2 billion years.
How does a red giant star compare to the sun?
A red giant star is much larger and brighter than the Sun. It is in the later stages of its life cycle when it begins to expand and cool down. Eventually, it will shed its outer layers and become a white dwarf.
