As a star expands into a red giant, the force of gravity increases in its core due to the increasing mass from the outer layers collapsing inward. This gravitational force causes the core to compress and heat up, leading to the fusion of helium and heavier elements. The balance between gravitational force and the pressure from nuclear fusion is crucial in determining the star's evolution during this phase.
What else can I help you with?
The star begins to run out of fuel and expands Into a red giant or red super giant?
No. That is when stars run out of hydrogen. They then have helium for fuel.
Why does an expanding giant star become more luminous?
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.
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 happens during the third stage of a stars life cycle as the star uses up all of its hydrogen?
During the third stage, a star expands and becomes a red giant as it runs out of hydrogen fuel in its core. The core contracts and heats up, causing the outer layers to expand. Eventually, the star will shed its outer layers to form a planetary nebula, leaving behind a dense core called a white dwarf.
What force makes a red super giant collapse?
a strong gravitational force which means that the star will collapse in on itself
When heavier elements form by fussion a massive star expands into a what?
When heavier elements form by fusion, a massive star expands into a red supergiant. This is a stage of stellar evolution where the star increases in size and becomes much more luminous.
What star expands 100 times its former size?
a red giant
As heavier elements are formed by fusion a massive star expands into a what?
A super giant
What forms when a main sequence star that has been contracting suddenly cools and expands?
A red giant forms when a main sequence star that has been contracting suddenly expands and cools.
The star begins to run out of fuel and expands Into a red giant or red super giant?
No. That is when stars run out of hydrogen. They then have helium for fuel.
What is a star that has exhausted its supply of hyderogen?
A star that has used up it's hydrogen supply because a "Red Giant". The star increases in diameter as it turns into a red giant.
Why does an expanding giant star become more luminous?
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.
Who are the giant scales in mega man star force Pegasus?
the giant scales is Librascales
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 formed when an average size star uses up it's fuel and it outer layer expands?
A Red Giant
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.
Which is a star in its old age Protostar Main sequence Black Hole or Red giant?
A red giant is a star in its old age. During this stage, a star expands and cools as it exhausts its hydrogen fuel. Eventually, it will shed its outer layers, forming a planetary nebula.
