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.
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.
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.
Is the main sequence lifetime of a low mass star the same as the lifetime of the sun?
No. The less massive a star, the longer it will last. A main sequence star half the mass of the sun can be expected to last about 5 times longer.
The star 61 cygni B has a main sequence lifetime of about how many years?
The star 61 Cygni B is estimated to have a main sequence lifetime of approximately 10 billion years.
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 percentage of a star's total lifetime is spent on the main sequence?
Roughly 90% of a star's total lifetime is spent on the main sequence, where it fuses hydrogen into helium in its core. After this stage, the star will evolve off the main sequence and follow a different path, such as becoming a red giant or a supernova.
Where does a star spend most of its lifetime on the h-r diagram?
On the main sequence.
What is a star's main fuel during its lifetime?
A star's main fuel during its lifetime is hydrogen. Through nuclear fusion processes in the star's core, hydrogen is converted into helium, releasing vast amounts of energy in the form of light and heat. This fusion process sustains the star's energy output and keeps it shining bright.
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.
Where does a star spend most of its lifetime on an h r diagram?
MAIN-SEQUENCE The average star spends 90% of its life as a hydrogen burning MS star.
Have scientists seen a star form or witnessed the formation of a star?
Not exactly: Star formation is believed to be a slow process, compared to a human lifetime; scientists have, however, seen stars in different phases of their formation.
