Does a red giant start have fusion occurring in its core?
Yes, a red giant is a stage in the life cycle of a star where fusion reactions are occurring in its core. The core of a red giant star typically consists of helium undergoing fusion into heavier elements like carbon and oxygen.
When the outer envelope of a red giant recedes the remaining carbon core is called?
When the outer envelope of a red giant recedes, the remaining carbon core is called a white dwarf. This core is extremely hot and dense, with no nuclear fusion taking place.
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.
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 red giant in Cetus?
In the constellation Cetus, there are several red giant stars. These are stars that have exhausted their core hydrogen and expanded in size. One notable red giant in Cetus is Menkar, also known as Alpha Ceti.
What are white dwarfs generally formed from in space?
White dwarfs are the exposed core of a dying star. They are formed when small or medium-sized stars age and became a red giant, then the outer layers of the red giant drift into space, leaving a hot core in the center, that core is a white dwarf.

What is a red giants core called?
A red giant's core is called a helium core. This is because as a red giant forms, the core of the star contracts and heats up, causing hydrogen fusion to transition to helium fusion.
How are giant stars and white dwarf related?
A giant star is a dying star that expanded, and the core shrinks are the same time. When the shell of the giant star drift into space as planetary nebula, the core became a white dwarf. The white dwarf is made from the core of the giant star.
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.
Are red giants stars the youngest?
No. Unless a star is a red giant (in which case it is old and dying) a red color does not indicate anything about its age.

When the outer envelope of a red giant recedes, the remaining carbon core is called a white dwarf. This core is extremely hot and dense, with no nuclear fusion taking place.

How does a stars temperature change as the star ages from main sequence star to a red giant and from a red giant to a white dwarf?
A regular stars temperature cools as it balloons into a red giant. The color shift is evident by the word red because red is the coolest color of heat. The surface of a dying star is cool because it is so much farther away from the core than when it is on the main sequence. After a star sheds its 'skin' the only thing that is left is the white hot core, which will eventually dim to a brown dwarf which is nothing but the cool charred remains of the white dwarf and will give off little to no light.
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.
How a star becames a white dwarf?
A white dwarf is the core of a dead star. As the star runs out of fuel, it expands into a red giant, as the shell of the red giant became a planetary nebula, and the core shrinks and became a white dwarf.
What is red giant in Cetus?
In the constellation Cetus, there are several red giant stars. These are stars that have exhausted their core hydrogen and expanded in size. One notable red giant in Cetus is Menkar, also known as Alpha Ceti.
