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 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 the name for the portion of a star's life cycle when it uses hydrogen for fuel?
The portion of a star's life cycle when it uses hydrogen for fuel is called the main sequence stage. During this stage, the star fuses hydrogen to form helium in its core, releasing energy in the process. This is the longest and most stable stage in a star's life.
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.
What is star fuel?
hydrogen
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.
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.
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.
What is a star that expands due to fusion?
A star that expands is running low on fuel, and is entering its end-of-life sequence. Its not due to fusion - all stars use fusion.
What happens when a star burns all of its hydrogen?
When a star burns up all of its hydrogen,it becomes red in color.As hydrogen is the fuel for star and it will burst after it.
What is the lifetime on the main sequence of a 2 solar mass star?
not very long because its about to supernova,,,,,,,,, i think again
