Complete Question here:
For three mass stars (a) a star with a mass three times the mass of the sun, (b) a star with a mass 5 times mass of the sun and (c) a star with a mass 20 times the mass of the sun
--> in each case describe the possible final state of the star after all its fuel is exhausted.
--> comment on the masses, size and density of these states.
--> for each of the end states, briefly describe experimental observations that allow us to find, identify, and verify the existence of object left after star has exhausted its fuel and collapsed to a final state. As an example how do we know that neuron stars exist.
A star 8 times the mass of the sun will most likely explode in a supernova.
A Neutron Star.
The Sun is a medium mass star on the main sequence.
No. The Sun is of fairly ordinary mass, and isn't NEARLY big enough to undergo a supernova explosion that would collapse the core to neutron star density. In fact, the minimum mass for a star that will die that way is about 3 times the mass of the Sun.
It's not got an exact definition, but astronomers usually mean a star of about 8 times the mass of the Sun or higher.
It will have a shorter lifetime. The Sun should last about 10 times longer.
During last ages of life of a star, to find what happens in coming ages of life of star. It determines on its mass explained by chandrashekher that if the mass of given star is 2.42 times the mass of our sun then it explodes in the form of supernova. If the mass of given star is less than the 2.42 times the mass of our sun then it shrinks to become white dwarf.
a neutron star
A star 8 times the mass of the sun will most likely explode in a supernova.
A Neutron Star.
The largest star (sun) has about 2000 times the diameter of our Sun. The most massive star has approximately 200 times the mass of our Sun.
It forms a "neutron star".
a star of about sun's mass will become a white dwarf star and will fade slowly into a black dwarf. a star of sun's 1.4 to 3 time the mass of the sun will become a neutron star. a star of more than 3 times of mass of the sun will become a black hole. hopes its help!!
Not sure what you mean with "land mass". It is a star, therefore it won't have land. Total mass is estimated to be 0.31 times the mass of the Sun (according to information in the Wikipedia).Not sure what you mean with "land mass". It is a star, therefore it won't have land.

a white dwarf
no the sun is a medium mass star.
If the sun was gone, the sun is a star, it would take Earth about 8minutes 30seconds for the people of earth to realise that the Sun was gone. But in the galaxy, there are millions of starts. A star is 1,000,000 times bigger than the mass of the Earth. A star can not be directly on Earth it would melt Earth.
