A double-shell burning red giant star is a late-stage stellar object that has exhausted hydrogen in its core and is undergoing nuclear fusion in two separate shells: one surrounding the core where helium is fusing into carbon, and the other where hydrogen is fusing into helium. This structure results from the star's expansion and cooling as it evolves off the main sequence. Such stars are characterized by their large size, high luminosity, and distinctive reddish hue due to their cooler surface temperatures. Eventually, they will shed their outer layers, leading to the formation of a planetary nebula and leaving behind a white dwarf core.
What else can I help you with?
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.
What is the main sequence of the red giant?
The main sequence of a red giant refers to the phase in a star's life cycle prior to its expansion into a red giant. During the main sequence, a star fuses hydrogen into helium in its core, generating energy that counteracts gravitational collapse. Once the hydrogen is depleted, the core contracts and heats up, leading to the outer layers expanding and cooling, which transforms the star into a red giant. Thus, the main sequence is characterized by stable hydrogen burning, while the red giant phase marks the transition to helium burning and further stellar evolution.
What is a real example of a red giant star?
Betelgeuse is a red giant.
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.
Is a red giant a main sequence star?
No, a red giant is a star that has just left the hydrogen burning main sequence and begun the next step, burning helium. As helium undergoes fusion at a much higher temperature than hydrogen undergoes fusion, the star expands dramatically and as it expands its outer layers cool to red heat.

Is UY Scuti a red giant star?
Yes, UY Scuti is a red supergiant star, which is a type of star that is larger and brighter than a red giant star.
What is a real example of a red giant star?
Betelgeuse is a red giant.
What is the name of red giant star?
Its justa red giant or supergiant
What do we call a large family of millions of stars?
Red giants. By the way, what if it was a white star.
Is the Dubhe star a red giant?
Dubhe is not a red giant but rather a subgiant star. It is the brightest star in the Big Dipper asterism and is classified as an evolved F-type subgiant star.
What class is the star Betelgeuse?
It is a Red Giant.
How do you use red giant in a sentence?
Our sun is expected to become a red giant within a few billion years. The red giant star Antares has a diameter 800 times that of the Sun.
