What is an expanding star after exhausting its hydrogen fuel called?
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.
What is Yellow dwarf star cycle?
A yellow dwarf star, like our Sun, undergoes a life cycle that begins with its formation from a nebula of gas and dust. It spends the majority of its life in the main sequence phase, where it fuses hydrogen into helium in its core, producing energy and maintaining stability. After exhausting its hydrogen fuel, the star expands into a red giant, eventually shedding its outer layers and leaving behind a hot core. This core, known as a white dwarf, will gradually cool and fade over billions of years.
What does a star become when it expands and outer layers cool?
When a star expands and its outer layers cool, it becomes a red giant. This occurs in the later stages of a star's life cycle, particularly for stars with masses similar to the Sun. The expansion is caused by the star running out of hydrogen fuel in its core and beginning to fuse helium into heavier elements.
Which star expands due to fusion?
As a star ages and runs out of fuel in its core, it can expand in size as it transitions into a red giant. During this phase, fusion reactions occur in the outer layers of the star, causing it to expand and cool. This expansion happens when the star exhausts its hydrogen fuel and begins fusing helium in its core.
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.
What is an expanding star after exhausting its hydrogen fuel called?
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.
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 7 stages are in the life of a star?
Nebula - a cloud of gas and dust in space. Protostar - a contracting cloud of gas and dust with increasing temperature and pressure. Main Sequence Star - a stable phase where a star fuses hydrogen into helium in its core. Red Giant - a phase where a star expands and cools after exhausting its hydrogen fuel. Helium Burning - a phase where helium fuses into heavier elements in the core. Planetary Nebula - a phase where a star sheds its outer layers into space. White Dwarf - a hot, dense remnant of a star that has burned out.
When a sunlike stars hydrogen runs out it expands into what?
When a sunlike star exhausts its hydrogen fuel, it expands into a red giant. During this phase, the star's core contracts and heats up, allowing helium fusion to begin. As it expands, the outer layers cool and become more luminous, giving the star its red appearance. Eventually, the outer layers are ejected, leaving behind a hot core that becomes a white dwarf.
What is star fuel?
hydrogen

What is the fourth stage of a star?
the fourth stage of a star is "supergiant" and its also the hottest stage
When the core of a star shrinks after hydrogen fusion stops the core heats up but what happens to the star?
The rest of the star expands.
If a star is the same mass as the sun for how many years can it fuse hydrogen and helium?
A star with the same mass as the Sun can fuse hydrogen in its core for about 10 billion years. After exhausting its hydrogen fuel, it will then enter the helium fusion phase, which lasts for around 100 million years. Therefore, while hydrogen fusion dominates its life, helium fusion is a much shorter process.
What inevitably forces a star like the Sun to evolve away from being a main sequence star?
The main factor that causes a star like the Sun to evolve away from being a main sequence star is the depletion of hydrogen fuel in its core. As the hydrogen fuel is used up, the core contracts and heats up, leading to the outward expansion of the star's outer layers. This expansion and change in structure lead the star to evolve into a red giant.
Which star expands due to fusion?
As a star ages and runs out of fuel in its core, it can expand in size as it transitions into a red giant. During this phase, fusion reactions occur in the outer layers of the star, causing it to expand and cool. This expansion happens when the star exhausts its hydrogen fuel and begins fusing helium in its core.
