Does the blue main-sequence star have a longer life than other stars?

It depends on the mass of the star. The lower the mass, the longer it will stay on the main sequence. A red dwarf may stay on the main sequence for trillions of years, while a blue star only lasts a few million years.

Wiki User
∙ 14y agoThe least massive stars stay on the main sequence the longest since they don't go through their fuel (their hydrogen) as quickly as bigger stars do. This is because bigger stars have to fight against more gravity, so they have to fuse their hydrogen at a faster rate than smaller stars. Once a star stops fusing hydrogen into helium at its core (and starts fusing heavier elements or just stops fusion altogether), it leaves the main sequence.

Main sequence is a misnomer; All Stars are Main sequence whilst they are converting Hydrogen to Helium, no matter the size or colour. Once this process ends so does the Title Main sequence.

As to a type of star from it's original formation, an O type star.

Is the sun hotter or cooler than red and blue stars?
The sun is hotter than red stars but cooler than blue stars,
Why are some stars red?
The spectral class of a star is dictated by its temperature. Hotter stars around 30,000K and higher tend to appear blue or bluish-white. At the other end of the spectrum, stars around 1,000-2,000K seem red. For more information see spectral classification, theory of stellar evolution, and the H-R diagram.
What do blue stars expand to become?
Blue giants.
How will you relate the type of stars to their temperature?

Why are there no stars bluer on the main sequence?
No stars blue? A star's colour depends on it's temperature. A blue star must be very hot in order for it to glow blue. All stars in the main sequence sre only hot enought to glow yellow, not hot enought to glow blue.
Are blue stars more luminous?
Blue stars are more luminous than other main sequence stars but not necessarily brighter than giant and supergiant stars.
Are blue stars cooler than red stars?
No, blue stars are hotter than red stars. In other words, red stars are cooler. Think of it as fire. The red one is hot, but the blue flame is RAGING hot.
How do blue stars differ from the red stars?
Blue stars are hot, and red stars are cold. You'd think it would be the other way around, but weirdly enough, it's not.
Do blue or yellow stars live longer?
Blue Star- blue stars the super giants of the sky. they are much larger than yellow stars (about 3 times bigger) and hotter. Yellow Stars- yellow stars are a lot smaller and cooler an example is our sun. Therefore, because blue stars are hotter than yellow- they burn their nuclear fuel a lot faster and live for a shorter time.
Do blue giant stars have a much longer life than the sun?
No. They have a much shorter duration.
Are blue stars younger than red stars?
Not necessarily. Blue stars are short-lived compared to other stars, so they can never be very old, but a red dwarf star can be any age.
Are all young main sequence stars blue?
No. Only the most massive main sequence stars are blue. Because blue stars are short-lived compared to other stars they are almost invariably young. Less massive stars live much longer, so only a fairly small portion of them are so young. For example a star like our sun can be expected to remain on the main sequence for about 10 billion years, if the rate of formation of such stars is constant then you can expect 1 in every 1,000 such stars to be in their first 10 million years on the main sequence.
What color are stars when they are really hot compared to their color when they are not as hot?
The hottest stars are blue or blue-white, the coldest stars are red. In between, from colder to hotter are orange and yellow and maybe green. A white dwarf star is even hotter than a blue-white star, but it is dead and no longer undergoing fusion.
Which is cooler the blue stars or the red stars?
Red stars are cooler than blue stars
Why is the sun yellow not red or blue like some other stars?
Other yellow-white stars like our sun do exist. The color of a star depends on its temperature. The coolest stars are red while the hottest are blue. Our sun falls in the middle of this range.
Are blue-white stars the coolest?
No. Red stars are the coolest. Blue stars are the hottest.
Are blue stars real?
Yes. The hottest stars are blue.
