The approximate lifetime of a small star, like a red dwarf, can range from tens of billions to over a hundred billion years. These stars burn their hydrogen fuel slowly, allowing them to exist for much longer than larger stars, which have shorter lifespans due to their more rapid fusion processes. In contrast, larger stars may only last a few million to a few billion years before exhausting their fuel. Overall, small stars are among the longest-lived objects in the universe.

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.
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.
what is a collapsed star ?
A collapsed star is a term used to describe a "dead" star, which is a star that has come to the end of its lifetime and just collapses on itself. A black hole
Where does a star spend most of its lifetime on the h-r diagram?
On the main sequence.
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 approximate lifetime of a heating coil on an electric dryer whirpool?
A lifetime - unless it breaks.
How does a star's mass indicate lifetime?
When a star is at the end of its lifetime its mass increases.
How is the lifetime of a star comparable to stellar evolution?
Stellar evolution is the term for the changes a star undergoes during its lifetime.
How does a stars mass indicate its lifetime?
When a star is at the end of its lifetime its mass increases.
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.
How many years does a star lives?
It depends on the size. Small, dim stars live much, much longer than large, bright ones. The expected lifetime of a star like the Sun as a main-sequence star is about 10 billion years.
Which star has a radius of 10 km?
That's the approximate radius of a neutron star, a.k.a. a pulsar.
How long does an massive star live?
The lifetime of a star varies a lot, depending on its exact mass. The lifetime of a star can be anywhere from just a few million years for the most massive stars, to trillions of years for red dwarves.
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.
What is the expected main sequence lifetime of wolf 359 a very dim star having 10 percent of the suns mass?
Wolf 359, with about 10% of the Sun's mass, is classified as a red dwarf star. Such stars have very long main sequence lifetimes due to their low mass and efficient hydrogen-burning processes. The expected main sequence lifetime of Wolf 359 is estimated to be around 10 to 30 billion years, significantly longer than the Sun's approximate 10 billion-year lifetime. This longevity is a characteristic feature of low-mass stars.
what is a collapsed star ?
A collapsed star is a term used to describe a "dead" star, which is a star that has come to the end of its lifetime and just collapses on itself. A black hole
How does a stars mass indicate?
When a star is at the end of its lifetime its mass increases.
