In the Main Sequence, stars can lose 1/3 to 1/2 of their initial mass when going from a Sun-like star to a red giant, to a white dwarf. An Earth-sized white dwarf will typically have an oxygen-carbon core but extremely high density, containing so-called "electron degenerate" matter.

What is the general relationship between a star's mass and its lifetime A. The greater the mass of a star the longer the star's life. B. The greater the mass of a star the shorter the star's life. C.?
B. The greater the mass of a star, the shorter the star's life. Massive stars burn through their nuclear fuel much more quickly than smaller stars, leading to shorter lifespans. While smaller stars can exist for billions of years, massive stars may only last a few million years before they exhaust their fuel and undergo explosive deaths, such as supernovae.
How the lifetime of stars depend on their mass?
The lifetime of a star is determined by its mass because more massive stars burn through their fuel faster due to higher core temperatures and pressures. Higher-mass stars undergo fusion at a quicker rate, leading to a shorter lifespan compared to lower-mass stars. Conversely, lower-mass stars burn their fuel more slowly, allowing them to exist for billions of years.
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.
How long a star lives depends on?
The suns mass. More massive stars have much higher temperatures and pressures. Although they have a lot more fuel (hydrogen), it is consumed at a much higher rate than lower mass stars. They burn very brightly and hot, but for less time.
What affects the luminosity of a star?
The total amount of light that the star radiates each second.
How does a star's mass indicate lifetime?
When a star is at the end of its lifetime its mass increases.
How does a stars mass indicate its lifetime?
When a star is at the end of its lifetime its mass increases.
What are the remnants of a high mass star?
Massive stars become neutron stars, or black holes (depending on how much mass is left at the end of a star's lifetime).
How does a stars mass indicate?
When a star is at the end of its lifetime its mass increases.
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.
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.
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.
How long a star lives depends on its'?
The lifetime of a star depends on the amount of fuel a star has, and the rate at which it fuses it. This can better be described as it's mass and it's luminosity.
Main sequence lifetime is determined by what?
The mass of the star. The bigger it is, the faster it will burn through its fuel supply.
What dose the lifetime of a star depend on?
Mainly its mass. The most massive stars develop the most quickly.
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.
What happens to a star that has twice the mass of the sun?
It will have a shorter lifetime. The Sun should last about 10 times longer.
