Is white dwarf a massive star?
No. A white dwarf is the remnant of a low to medium mass star.
What is the relationship between a black hole and a neutron star?
Think of a black hole like the neutron star's big brother. When a star reaches the end of its life, it blows off its outer layer in a supernova and leaves behind a stellar remnant. The mass of the star, during its life, determines what is left behind by its death. For relatively low mass stars (such as our own star), the remnant is a white dwarf. Get much larger than about 1.4 times our own star's mass and you end up with a neutron star. The exact upper mass limit for neutron star formation isn't known for certain, but the estimate is something between 2 and 3 times our own star's mass. Above that, and the remnant core collapses into a black hole.
Why would a white dwarf become a red dwarf?
A white dwarf could not become a red dwarf. A white dwarf is a remnant of a dead star. A red dwarf is a star with a very low mass.
Is juveline star a low mass star or a high mass star?
It may be either. Juvenile means young.
Is the sun a low mass or high mass star and which stage is it in?
The Sun is a medium mass star in main sequence.
Are white dwarf stars a low mass star?
A white dwarf is the remnant of a low to medium mass star.
Is white dwarf a massive star?
No. A white dwarf is the remnant of a low to medium mass star.
Is a white dwarf bigger than a main sequence?
No. A white dwarf is the collapsed remnant of the core of a low to medium mass star. It has a mass comparable to that of a star, but is about the size of a small planet.
Is a brown dwarf star on its way to becoming a black dwarf?
No. A brown dwarf is a star that has too low a mass to start nuclear fusion. A black dwarf is a former white dwarf, the remnant of a low to medium mass star that ran out of fuel in its core.

What is the difference between the protostar and the white dwarf?
A protostar is a star that is in the early stages of formation that has not yet become a main sequence star. A white dwarf is a remnant left behind after a low to medium mass star dies.
What remnant does a supernova leave?
Depending on the mass of the original star, it is either a black hole or a neutron star.
Why would a white dwarf become a red dwarf?
A white dwarf could not become a red dwarf. A white dwarf is a remnant of a dead star. A red dwarf is a star with a very low mass.
Is a white dwarf considered a main sequence star?
No, a white dwarf is not considered a main sequence star. A main sequence star is a star that is still fusing hydrogen in its core. A white dwarf is the remnant of a low to medium mass star in which fusion has stopped.
Is the Rigel star a high mass star or a low mass star?
High mass.
What element does a low mass star stop at and why?
Helium. A low mass star does not have enough mass to generate the heat needed to fuse helium.
Is the sun a low mass or high mass sequence star?
The sun is an intermediate-mass star.
