Do high mass stars have shorter lifetimes than low mass stars?
–High-mass main-sequence stars have shorter lifetimes than those of lower-mass stars because high-mass stars burn their fuel at much faster rates. -High-mass main-sequence stars have longer lifetimes than those of lower-mass stars because they have a much larger supply of nuclear fuel.
Which have longer main sequence lifetimes low mass stars or high mass stars?
A main sequence star is powered by fusion of hydrogen into helium in its core. Fusion is stabilized by a natural pressure-temperature thermostat. High-mass main sequence stars have shorter lifetimes than low-mass main sequence stars.
Which stars have the longest main sequence lifetimes?
The stars with the longest lifetimes are red dwarfs; some may be nearly as old as the universe itself.
Do smaller stars have longer lifetimes?
A smaller star has less fuel, but its rate of fusion is not as fast. Therefore, smaller stars live longer than larger stars because their rate of fuel consumption is not as rapid.
Why do high mass stars have shorter life spans?
A star’s life expectancy depends on its mass. Generally, the more massive the star, the faster it burns up its fuel supply, and the shorter its life. The most massive stars can burn out and explode in a supernova after only a few million years of fusion.
How long do stars stay on the main sequence?
While the sun will spend about 10 billion years on the main sequence, a star 10 times as massive will stick around for only 20 million years. A red dwarf, which is half as massive as the sun, can last 80 to 100 billion years, which is far longer than the universe’s age of 13.8 billion years.
Why do high mass stars have shorter lifetimes?
This equation states that the larger the mass of the star, the shorter the lifetime. This is because the fuel consumption gets huge for the more massive stars. Even if massive stars have more fuel, the consume it at such intensely high rates that they don’t live as long as lower mass stars.
Is greater for low mass stars than it is for high mass stars quizlet?
1. The MAIN-SEQUENCE LIFETIME is greater for low-mass stars than it is for high-mass stars. 2. The stars known as SUPERGIANTS are the very largest and brightest of all the stars.
Which main sequence stars have the shortest lifetimes?
-Stars on the main sequence are happily converting hydrogen to helium in their cores – stable (for now). –O stars have the shortest lifetimes (less than 10 million years).
Which stars have longer lifetimes quizlet?
Less massive stars have longer lifetimes because they are burning the hydrogen in their cores at a slower rate than more massive stars.
Why are main sequence lifetimes shorter for more massive stars quizlet?
Why does mass determine the main-sequence lifetime of a star? Because more massive stars burn fuel faster and therefore have shorter lives.
Why do high mass stars burn faster?
The extra gravitational pull compresses both the core and the hydrogen-burning shell around it. As the hydrogen-burning shell becomes denser, it becomes hotter and burns hydrogen at a faster rate, making the star even brighter and larger.
Why do high mass stars age faster than low mass stars?
The more luminous they are, the more reactions are taking place in their cores. Massive stars live shorter lives than the common small stars because even though they have a larger amount of hydrogen for nuclear reactions, their rate of consuming their fuel is very much greater.
Why do you think massive star has shorter life span than average stars Brainly?
A massive star has a shorter life span than an average star because of faster hydrogen fuel consumption by a massive star. Massive stars have shorter lives than common small stars because, despite having more hydrogen for nuclear reactions, they consume their fuel at a much faster pace because of their very large size.
What stars are not much larger in radius than Earth?
WHITE DWARFS: Not much larger in radius that Earth, very hot but very dim.
Which of the following comparisons between low mass stars and high mass main sequence stars is true?
Which of the following comparisons between low-mass stars and high-mass main-sequence stars is true? Low-mass stars are cooler and less luminous than high-mass stars.
Which star has the largest radius quizlet?
Which star has the largest radius? According to the notes, “stars with a higher L and lower T than the MS have larger radii and that these stars are giants and supergiants”. Antares would have the largest radius because it is the supergiant on this chart.
What type of star has a high temperature but a low luminosity?
What type of star has a high temperature but a low luminosity? White Dwarf 18.
Which main sequence star has the largest mass?
The largest known star is UY Scuti, a hypergiant with a radius somewhere around 1,700 times larger than the sun. Its mass, however, is only 30 times that of our nearest star. If R136a1 swapped places with the sun, it would outshine our closest star as much as the sun currently outshines the moon.
What main sequence stars have the lowest mass?
Z Z certainly has the lowest mass on the main sequence. It will not evolve off the main sequence for a very long time, so the evolved stars are almost certainly more massive.
What happens to the core of a high-mass star after it runs out of hydrogen?
What happens to the core of a high-mass star after it runs out of hydrogen? It shrinks and heats up.
Which mass star becomes the most luminous?
Which mass star becomes the most luminous? The 40 solar mass star has the highest luminosity at 425,402.46 solar luminosities.
Which kind of star is hottest quizlet?
(Notice that temperature is related to color, and follows the order of the colors in the rainbow: Blue (or violet) stars are the hottest, while red stars are the coolest.)
What happens to a high mass star?
When a high-mass star has no hydrogen left to burn, it expands and becomes a red supergiant. While most stars quietly fade away, the supergiants destroy themselves in a huge explosion, called a supernova. The death of massive stars can trigger the birth of other stars.
What is the difference between high mass and low mass stars?
Both, a low mass Star and a High mass Star will Start off with fusing hydrogen into Helium, though a high mass Star will burn it faster because of increased pressure and temperature in the core. A second difference is the ability to create heavier elements.
Are high mass or low mass stars more common?
Which is more common low mass stars or high mass stars? Low mass stars are far more common.
Why is there an upper mass limit for main-sequence stars about 100 solar masses group of answer choices?
Objects below this mass are not hot enough to fuse normal hydrogen. Why is there an upper mass limit for main-sequence stars of about 100 solar masses? Objects above this mass fuse hydrogen too rapidly and cannot stay together.
What are 2 characteristics of high mass stars?
High mass stars (stars with masses greater than three times the mass of the Sun) are the largest, hottest and brightest Main Sequence stars and blue, blue-white or white in colour. High mass stars use up their hydrogen fuel very rapidly and consequently have short lives.
How do the stars radii compare with their mass?
Answer: The radii of main-sequence stars increases as mass increases.
Why do lower mass stars burn for a longer time quizlet?
Terms in this set (16) Stars that begin their lives with the most mass live longer than less massive stars because it takes them a lot longer to use up their hydrogen fuel.
What effects will the efficient fusion and high core temperatures have on high mass stars?
What effects will the efficient fusion and high core temperatures have on high-mass stars? They will burn through their hydrogen more quickly, owing to both the efficiency of the CNO cycle and the higher core temperature.
Are bigger stars brighter?
Larger stars usually shine more brightly than smaller stars do. So, how bright a star appears in the night sky depends on its size and how far away from us it is.
Are the hottest stars the brightest?
Explanation: Bright main sequence stars tend to be larger and hotter. The notable exception to this are red giants.
Which of the following is true about low mass stars compared to high mass stars quizlet?
Which of the following is true about low-mass stars compared to high-mass stars? Low-mass stars are cooler and less luminous than high-mass stars.
What change slowly occurs during the main sequence lifetime of a star?
What change slowly occurs during the main-sequence lifetime of a star? Its core temperature slowly increases, increasing the fusion rate and hence the luminosity.
Which is more common a star blows up as a supernova or a star forms a planetary nebula white dwarf system quizlet?
Which is more common: a star blows up as a supernova, or a star forms a planetary nebula/white dwarf system? Supernovae are more common. They both occur in about equal numbers.
Which stars have the largest radius?
The largest known star in the universe, UY Scuti is a variable hypergiant with a radius around 1,700 times larger than the radius of the sun. To put that in perspective, the volume of almost 5 billion suns could fit inside a sphere the size of UY Scuti.
Which type of star is the brightest quizlet?
Giants and supergiants tend to be the brightest stars in the sky. They are very luminous due to their large size.
Which star has a greater luminosity?
Name | Constellation | Bolometric luminosity (Solar lum.) |
---|---|---|
Sun | 1 | |
Alpha Centauri A | Centaurus | 1.519 |
Sirius | Canis Major | 25.4 |
Vega | Lyra | 40.12 |
What is a high mass star?
High-mass stars are very luminous and short lived. They forge heavy elements in their cores, explode as supernovas, and expel these elements into space. Apart from hydrogen and helium, most of the elements in the universe, including those comprising Earth and everything on it, came from these stars.
How big are high mass stars?
An example of a high-mass star is the red supergiant Betelgeuse; it is 500 times the size of our Sun. This supernova occurred about 168,000 ly from Earth. High-mass stars have lives of 10 million years, versus 10 to 50 billion years or more for low-mass stars.
Why do high mass stars age faster than low mass stars?
A star’s life expectancy depends on its mass. Generally, the more massive the star, the faster it burns up its fuel supply, and the shorter its life.
Why do small stars have longer lifetimes than large stars?
A smaller star has less fuel, but its rate of fusion is not as fast. Therefore, smaller stars live longer than larger stars because their rate of fuel consumption is not as rapid.
Why is there a lower limit to the mass of a main sequence star?
Why is there a lower limit to the mass of a main-sequence star? Objects with masses lower than 0.08 of the suns mass cannot raise their central temperature high enough to sustain hydrogen fusion.
Which stars live the longest lives on the main sequence the shortest Why?
The most massive stars have the shortest lifetimes. Because they have most fuel, they burn it so prodigously that their lifetimes are very short.
What stars have a high temperature?
Type O stars have the highest surface temperatures and can be as hot as 30,000 Kelvins.
Which star has highest temperature?
Systems like this are estimated, at most, to represent 0.00003% of the stars in the Universe. The hottest one measures ~210,000 K; the hottest known star. The Wolf-Rayet star WR 102 is the hottest star known, at 210,000 K.
Why do supergiant stars such as Betelgeuse have high luminosity?
Supergiant stars that are old enough to be fusing helium instead of hydrogen. This process releases more energy, causing the star’s outer layers to swell.
