When a red giant reaches the end of its life and is unable to fuse any more elements, the core cools and collapses due to gravity. The outer layers are ejected and become a planetary nebula, and all that remains of the star is an extremely dense core, which is called a white dwarf.

When a main-sequence star has exhausted the fuel in its core it becomes a....?
I am pretty sure it becomes a giant if I'm not mistaken.
Which types of star has low temperature and high luminosity?
A red giant star.
Is red giant a star or a type of star?
Red giant is a type of star.
How does a star turn into a red giant?
A star turns into a red giant when it lose fuel and die. If a star isn't a massive star then it expands into a red giant. After that it becomes a white dwarf. If its massive then it collapses on itself and turns into a black hole.
When a main sequence has exhausted the fuel in its core it becomes?
The next step in its life is to become a "red giant" star.
What is the difference between a star that becomes a red giant and one that becomes a red supergaint?
The mass of the star.
When a main-sequence star has exhausted the fuel in its core it becomes a....?
I am pretty sure it becomes a giant if I'm not mistaken.
When an intermediate mass star enters the red giant stage of its life cycle what cause the star to give off a red glow?
As the star balloons into the red giant phase, its surface becomes further away from the core and cools. This changes the color appearance of the star from orange or blue to red.
What are the red giants?
A red giant is when a star becomes very large. A super red giant is when a star becomes very extremely large. People think that in a few billion years, our sun will become a red giant and swallow up earth.
What do you call a star that is bigger then a regular one?
first its called the main sequence star like the sun then it becomes a red giant then it becomes a red super giant and if it is huge a hyper-giant like VY Canis Majoris (largest star known) then it explodes and it becomes a planetary nebula then it becomes a white dwarf
What causes a giant?
After a star burns up all it's hydrogen, it becomes a red giant.
Does a red main sequence star have fusion?
A red main sequence star would be a red dwarf or a branch red giant. To be on the main sequence, you have to have hydrogen nuclear fusion.
