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 else can I help you with?
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.
Which best describes the very next phase in our sun's life cycle?
It will expand and become a red giant.
Stage where the star swells?
The stage where a star swells into a red giant is called the red giant phase, typically occurring when a star runs out of hydrogen fuel in its core and starts to fuse helium in its shell. During this phase, the star expands and cools, turning redder in color due to its lower surface temperature.
What will be the next stage in the sun's life cycle?
The next stage in the sun's life cycle will be the red giant phase. During this phase, the sun will expand and become bigger, eventually engulfing the inner planets of our solar system.
What is the next stage of the life cycle of the sun?
The next stage in the life cycle of the Sun is the red giant phase. During this phase, the Sun will expand and cool, becoming larger in size and engulfing planets, including Earth. This phase is followed by the shedding of its outer layers to form a planetary nebula, leaving behind its core as a white dwarf.
What are the stages of life for a blue giant star?
A blue giant star goes through multiple stages during its life cycle: formation from a collapsing nebula, main sequence where it fuses hydrogen into helium, red giant phase where it expands and fuses heavier elements, and finally, depending on its mass, it may end as a supernova or a black hole.

Which type of fusion occurs in the red giant phase?
The primary type of fusion that occurs in the red giant phase is helium fusion. As the star's core runs out of hydrogen fuel, it contracts and heats up to the point where helium fusion can begin, converting helium into carbon and oxygen. This process generates energy and causes the star to expand and become a red giant.
What is the 2 stage of the red giant?
The second stage of a red giant occurs after the core has contracted and heated up sufficiently to ignite helium fusion. This stage follows the initial hydrogen burning phase, where the star expands and cools, giving it a red hue. During this phase, helium in the core fuses into carbon and oxygen, while the outer layers continue to expand and cool. This process leads to the star becoming larger and more luminous before it eventually sheds its outer layers, forming a planetary nebula.
What is the next stage in the suns evolution?
The next stage in the Sun's evolution is the red giant phase. This occurs when the Sun runs out of hydrogen fuel in its core and starts burning helium. During this phase, the Sun will expand and become larger, eventually engulfing Mercury, Venus, and possibly Earth.
How many phases does the sun go through?
The sun primarily goes through three major phases in its life cycle: the main sequence, the red giant phase, and the final stages as a white dwarf. During the main sequence phase, which lasts about 10 billion years, the sun fuses hydrogen into helium. After exhausting its hydrogen fuel, it expands into a red giant, eventually shedding its outer layers. The remaining core then contracts into a white dwarf, which will cool and fade over billions of years.
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.
What if the biggest star went through a red giant phase?
The biggest star - VY Canis Majoris IS in a red supergiant phase and will explode as a massive supernova.
