Energy is absorbed in expanding and lifting the gas.
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.
A giant star would experience a supernova explosion, in order to become a white dwarf.
Beta Cancri (Tarf) is the brightest star in the constellation Cancer.It has a spectral type of K4 so it is a orange giant.
Pollux is a close binary star system located in the constellation of Gemini. It consists of a red giant star as the primary component and a smaller dwarf star orbiting around it. The primary star is nearing the end of its life and has expanded to become a red giant.
When fusion stops in a star it will start to fuse helium and will become a red giant.
Color is related to surface temperature, and a "red giant" is cooler than a main sequence, medium-sized star like the Sun.

It wouldn't be good
A star become a red giant when the core contracts, the temperature increases and the outer layers of the star begin to expand. By the end of this phase, the star can be 10 to 100 times it diameter. When the temperature in the core reaches 100 000 000°C, the helium start fusing into carbon. Because the star has expanded to such an enormous size, that the outer layer are much cooler than when the star was a main sequence star. It therefore appears red, earning the name of red giant.
As a giant star expands, its surface area increases, allowing more energy to escape from its core. This increased surface area results in the star appearing more luminous. Additionally, the expansion causes the outer layers of the star to become less dense, which allows more light to escape and contribute to its overall brightness.
That would mainly depend on the star's mass.
Capella is a binary star system located in the constellation of Auriga. It consists of two giant stars, Capella A and Capella B. Capella A is a yellow giant star, while Capella B is a smaller, cooler red giant star.
It's smaller and cooler. It will also live a lot longer than a blue giant.
A red giant star appears red in color due to its cooler surface temperature compared to other stars. The red color is produced by the cooler temperatures causing the star to emit more red light than other colors.
A supergiant star can have different colors depending on its temperature. A hotter supergiant star will appear blue or white, while a cooler supergiant star will appear red or orange.
it doesn't because the star may be already dead before its ready to become a giant.
Muliphien is a yellow giant star located in the constellation Canes Venatici. It is classified as a K-type star, which means it is cooler than our Sun.
