In what ways do the formative stages of high mass stars compare with those of Sun like stars?
In what ways do the formative stages of high mass stars differ from those of stars like the sun? higher mass stars tend to place higher on the H-R diagram. they become O-type stars in about 1/50 of the time it took the sun to become a star.
What factor determines how long a star lives?
The overall lifespan of a star is determined by its mass. Since stars spend roughly 90% of their lives burning hydrogen into helium on the main sequence (MS), their 'main sequence lifetime' is also determined by their mass.
What characteristics of a star cluster determine its age quizlet?
The age of a star cluster can be determined by the luminosity of the main sequence turnoff into the giant stage.
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.
What is the difference between the life cycle of a low mass star and a high mass star?
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.
How are the lives of a very low mass star and a very high mass different?
Low mass stars end their lives here, by expelling their outer layers due to thermal pulses in a planetary nebula phase, but high mass stars have so much mass that they can survive this phase. In our earlier analogy of a pressure cooker, high-mass stars have a heavy "lid," so they keep on cooking.
What single factor decides how long a star lives more than any other?
What factor determines how long a star lives? The amount of helium or carbon that is contained in a star.
What is the shortest lifespan of a star?
When a star is more than ten times as massive as the sun, it becomes a Supergiant star. Supergiants have the shortest lifespans of any star, as the temperatures in a supergiant's core get so high that it is able to fuse the helium that is left over after hydrogen burning has stopped.
What characteristic of a star cluster is used to determine its age group of answer choices?
Noting the turnoff mass in a star cluster allows you to determine its: age.
Which type of star cluster has a similar age and stellar content as which type of galaxy?
globular clusters Since globular clusters form at once from a single giant molecular cloud, a cluster's stars have roughly the same age and composition.
Why do big stars live longer?
The more fuel, the more supply of material for fusion the star has and so the longer the star can live. The fuel is hydrogen atoms and the number of hydrogen atoms is greater in high mass stars than it is in lower mass stars. Thus, the higher the mass of the star, the longer its lifetime can be.
How do stars live so long?
The length of a star's life depends on how fast it uses up its nuclear fuel. Our sun, in many ways an average sort of star, has been around for nearly five billion years and has enough fuel to keep going for another five billion years. Almost all stars shine as a result of the nuclear fusion of hydrogen into helium.
Why do you think massive star has shorter life span than average stars Brainly?
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.
How is the lifetime of a star related to its mass?
Massive stars are short-lived. A star's mass gives a measure of the amount of "fuel", and its luminosity gives a measure of the rate at which this "fuel" is consumed by nuclear burning, so a star's lifetime is proportional to its Mass divided by its Luminosity.
How does the life and death of a high mass star differ from the life and death of a low mass star?
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.
How does the energy transport differ from a high mass star to that of a low mass star like the Sun?
Energy Production A piece of the star has a lot of energy coming through it from below, and not much energy leaving from above. It can't move this energy fast enough by radiation, so convection kicks in. Low mass stars operate via the p-p chain, which has a relatively weak temperature dependance (E ~ T4).
Why do average stars have longer lifespan than massive star Brainly?
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 stars live so long?

Almost all stars shine as a result of the nuclear fusion of hydrogen into helium.
What is the longest lived star?
Red Dwarfs Red Dwarfs: The Most Common and Longest-Lived Stars | Space.
How long do the longest stars live?
The mass of a star defines its lifespan. The least massive stars will live the longest, while the most massive stars in the Universe will use their fuel up in a few million years and end in a spectacular supernova explosion.
How could we tell a very large star cluster from a very small Galaxy of the same size?
How could we tell a very large star cluster from a very small galaxy of the same size? a galaxy has lots of dark matter, a star cluster doesn't have dark matter of its own.
What happens to stars in a cluster as it ages How does mass affect this trend?
As time passes the most massive stars at the top of the main sequence evolve into red giants. Therefore, the older the cluster, the fewer stars to be found at the top of the main sequence, and an obvious grouping of red giants will be seen at the top right of the HR diagram.
How could we tell a very large star cluster from a very small galaxy of the same size?
How could we tell a very large star cluster from a very small galaxy of the same size? a galaxy has lots of dark matter, a star cluster doesn't have dark matter of its own.

Do small stars live longer?
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.
What is the shortest lived star?
Massive Stars Supergiants have the shortest lifespans of any star, as the temperatures in a supergiant's core get so high that it is able to fuse the helium that is left over after hydrogen burning has stopped.
Why are stars very massive?
When a nebula collects enough mass, it begins to collapse under its own gravity. The internal pressure created by this collapse is enough to trigger fusion of hydrogen deep in its core. When nuclear fusion begins, a star is born. If the cloud of dust is large, it will create a massive star.
In which stage do massive stars explode and release large amount of energy?
A supernova is the colossal explosion of a star. Scientists have identified several types of supernova. One type, called a “core-collapse” supernova, occurs in the last stage in the life of massive stars that are at least eight times larger than our Sun. As these stars burn the fuel in their cores, they produce heat.
What is the relationship between the mass of a star and how long the star will live quizlet?
What is the relationship between the mass of a star and how long the star will live? Higher mass stars live shorter lives.
