red dwarf
If its high mass it ends with neutron star of black hole and if its low mass it ends as a black dwarffor all stages check here What_are_the_stages_of_a_star's_life_cycle
It depends. If the star is a star the size of the Sun or smaller, then the core throws off much of its mass and becomes a white dwarf. The star eventually cools and dims over an extremely long period of time, becoming a black dwarf (there are no known stars at this stage).
If it's a massive star then the core collapses in less than a second, causing an explosion called a supernova, in which a shock wave blows off the outer layers of the star. Sometimes the core survives the explosion. If the surviving core is between 1.5 and 3 solar masses, it contracts to become a tiny, very dense neutron star. If the core is much greater than 3 solar masses, the core contracts to become a black hole, which is a concentrated mass called a singularity exerting massive gravity.
It depends on what star cycle they follow.
If the star is massive enough it will explode in a supernova. This burns off all the leftover energy of the star and the core will collapse into a black hole.
If it's mass is not great enough to cause a supernova then it will become either a neutron star or a black dwarf.
When a star is born it moves to the lower right path of the Main Sequence of the H-R Diagram (Phase one). This is where the star begins Hydrogen ---> Helium fusion. When a star runs out of Hydrogen the core cools and the outer layers expand forming a red giant. This is where the star on the Main Sequence moves off into the Giant Branch (Phase two). When the star regains Hydrostatic equilibrium (fuses Helium to Carbon) it moves to the Horizontal Branch (Phase three) where it spends a few months burning up all the Helium. When the star runs out of Helium, it's core cools and the outer layers expand, AGAIN, making the red giant become a red giant again (Super giant) in which it moves up the Asymptotic Branch (Phase four) the last phase the star waits to explode.
Asymptotic Branch is where the end of the star's life begins. This is the phase carbon is fused to every element up to Iron.
A star is dead once it ceases nuclear fusion in its core. Stars such as white dwarfs, neutron stars, and black holes are therefore 'dead' stars.

When the star starts fusing hydrogen in it's core.
A white dwarf, a neutron star or a black hole - depending on the amount of the remaining star's mass.
Nuclear fusion reactions begin and the protostar becomes a true star.

the color of the protostar is red
A "Star" can be anything from the beginning of a stars life (Protostar) up until it has died and only it's remnants remain (White dwarf, neutron star, black hole). However, for this question, we will assume that a "star" is when it is fusing hydrogen into helium, which is what most stars we see, including the Sun are doing. A protostar is the first stage in a stars life (See related question) whereas a "star" in this question is when there is enough pressure and thus temperature for the star to star fusing hydrogen into helium and it joins the main sequence - thus becoming a star (See related question)
Nuclear Fusion occurs in the core of stars.
The young star stage because at that stage, stars are just burning, no interruptions or disturbances
A Protostar.
"Binary" means there are two stars. And "protostar" means the stars are in an early, or preliminary, stage.
The term is "protostar", not "prostar". Yes. A protostar is an early stage of a star.
A protostar generates energy by friction whereas a main sequence star generates energy by fusion.
It doesn't differ from a star, it is a star and it is the second stage in a stars life after the nebula stage.
On the contrary, "protostar" is the name of an early stage in the development of a star.
star birth, protostar stage, main sequence stage, red giant stage, then burnout and death
the color of the protostar is red
It is called a protostar, as it is beginning to form the spherical shape and collecting hydrogen due to its growing mass and gravitational attraction.
Star Birth as a Protostar. Stars are born within molecular clouds in the Galaxy. The mass of a protostar determines its place on the H-R diagram, its energy source, its ultimate fate. Then, the final stage when the core is fused to iron.
the answer is a protostar
the answer is a protostar
