A star's lifetime depends on what?
A star's lifetime depends on its mass. More massive stars have shorter lifetimes, burning through their fuel faster, while less massive stars have longer lifetimes. Additionally, the composition of a star determines how it burns its fuel and influences its lifetime.
What is the primary fuel of main sequence stars?
The primary fuel for all stars is hydrogen
What is the main fuel for nuclear reactions in stars?
The main fuel for nuclear reactions in stars is hydrogen. Through a process called nuclear fusion, hydrogen atoms combine to form helium, releasing energy in the form of light and heat. This process powers the stars and allows them to shine brightly.
Are main sequence stars older than red giants?
No, red giants are generally older than main sequence stars, as red giants have no hydrogen left for fuel, and burn helium instead. where as Main Sequence stars burn hydrogen for fuel.
How does the main-sequence lifetime of a star compare to its entire fusion lifetime?
The main-sequence lifetime is a phase in a star's life when it fuses hydrogen into helium in its core. This phase typically lasts about 90% of a star's total fusion lifetime. After the main sequence, a star may continue to fuse other elements, depending on its mass, which will determine the total duration of its fusion lifetime.

What is a star's main fuel doing its lifetime?
For most of a star's life, the main fuel is protium (hydrogen-1), which is fused into helium-4.

What were the main cities during King Tut's lifetime?
karnak and kush

Main sequence lifetime is determined by what?
The mass of the star. The bigger it is, the faster it will burn through its fuel supply.
What fuel is used with the main sequence stars?
gas, and other vibrate radiations.
Which star has a shorter lifetime on the main sequence a blue O star or a yellow G star?
an o-type blue star has a less length life than a g-type sun like star, this is because a the larger, hotter star, (the o-type blue star) uses its fuel (converting hydrogen into oxygen) quicker, so the correct answer to your question is the o-type blue star.
What is the name of the portion of a stars life were it uses hydrogen as fuel?
A star that uses hydrogen as fuel is a main sequencestar.
What do all stars in main sequence have in common?
main sequence stars all are burning though fuel at asteadyrate in there cores. with the proton+proton chain our sun is a main sequence star
