Will a star's lifecycle be shorter or long if its mass is greater?

The way that a star's mass affects it's life span is that when a star is about the same size as our Sun, it's nuclear fusion process occurs much slower and therefore the star lives longer. However, with a high mass star, it's fusion process occurs much faster and therefore a high mass star has a much shorter life span than a low mass star.

∙ 14y agoRather unusually a stars lifetime is inversely proportional to its mass (and therefore radius and luminosity). This is because although the amount of fuel the star has does increase with mass, the rate at which it uses this fuel increases even faster. The approximate relation is that a Star's lifetime is proportional to (1/mass)^3. However this only applies to a stars lifetime on the main sequence.

Are shadows short or long in the morning?
Long, getting shorter towards noon.
What is long wavelength radiation given out by stars?
Infrared radiation is long wavelength radiation given out by stars.
How do the properties of long-lived stars compare to those of short-lived stars?
Long-lived stars begin their lives with less mass and a smaller amount of hydrogen fuel. and Long-lived stars are less luminous during their main-sequence lives.
Why are the youngest star are the blue stars?
Only very massive stars are blue. This is because they must burn hotter to resist the crush of gravity due to their large masses. They burn very hot, but also very fast so they have much shorter lifespans than less massive stars do. Therefore, blue stars are young because they become red supergiants and then go supernova fairly rapidly in star lifespan terms. They just do not last very long in the blue giant stage, so those stars, like Rigel in Orion, are young stars. If they were not, they would be red supergiants or neutron stars or black holes by now.
Are there 100-year-long storms on Mars?
There can be but there can be shorter ones and longer ones
When a star dies does its mass change?
If it explodes; yes. If it just goes out, then no. Note that large stars generally all explode to some degree (the more massive, the greater the explosion). The stars that don't are the small (red) stars that last a long, long time.
Which manufacturing layout is best suited for items that have a long lifecycle?
continuous flow
Why is it unlikely to find life around stars more massive than the sun?
The more massive a star is, the shorter it lasts. The most massive stars do not last long enough for life to develop on any planets around them. Some do not even last long enough for planets to form.
How many days does the bed bug live?
as long as you dont run them over in your teletubie pjs
Why don't astronomers see greater numbers of dwarf stars?
because it takes a star long time to reach at the stage. That's wahy the astronomers can't see the dwarfs stars, and also these stars are small you will have to foucus on it little hard.
Are true statements about a 30-60-90 triangle?
.The hypotenuse is twice as long as the shorter leg The longer leg is twice as long as the shorter leg.
Why is it important to study a product's lifecycle?
It is important to study a product's lifecycle to see how long it will last until it breaks,messes up, or gived way. -sincerely a Bridgeton High School student....DMR
Which swings more in30 secondspendulum that is 20cm long or one that is 40cm long?
The shorter pendulum has the shorter period.
Which of the following are true statements about a 30-60-90 triangle?
The hypotenuse is twice as long as the shorter leg AND The longer leg is 3 times as long as the shorter leg.
What is a long length of wire coiled up into a shorter length?
A shorter length
How can a lever generate a large force?
A lever works against a fulcrum. If there is a shorter section of the lever at one end of the fulcrum and a longer section at the other end, then you can exert a force on the longer end of the lever, and have a greater force exerted on the shorter end. That is because you are moving the long end through a longer distance than the shorter end moves, and all the force exerted over the longer distance is then effectively compressed into the shorter distance.
Are the arms of the common marmoset long or shorter than the legs?
The forelimbs are shorter in most Marmosets
