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.

How the lifetime of stars depend on their mass?
The larger a star the shorter the lifetime because, larger stars burn out more quickly.
Which star would live longer a star that has half the mass of the sun or a star that has 2 times the mass of the mass?
Stars with less mass live much longer. Stars with greater mass get hotter, and have more pressure in their core; as a result, they use up their fuel much faster.
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.
Which star has as much mass as the sun?
It would be difficult to define another star with the same mass as our Sun. Depending on your boundaries for selection criteria, and G2 star will be pretty close. Naming a star, then Alpha Centauri A would be fairly close.
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).
What determines the path a star will take during its lifetime?
The mass of the star
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 the lifetime of stars depend on their mass?
The larger a star the shorter the lifetime because, larger stars burn out more quickly.
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.
Is the sun a low mass or high mass star?
There are more low mass stars. this is for two reasons:- # the star forming process generates more low mass stars # High mass stars burn out very quickly and explode as supernovas and thus over time there are less and less of them.
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.
