What else can I help you with?
Is white dwarf a massive star?
No. A white dwarf is the remnant of a low to medium mass star.
Is Sirius b a high or low mass star?
Sirius B is a white dwarf. So it is low mass compared to other stellar remnants.
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.
What remains after a low-mass or medium-mass star dies?
After a low-mass or medium-mass star dies, it will typically leave behind a remnant called a white dwarf. A white dwarf is a dense, Earth-sized core made primarily of carbon and oxygen. It gradually cools and fades over billions of years.
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.
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 Sirius b a high or low mass star?
Sirius B is a white dwarf. So it is low mass compared to other stellar remnants.
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 young star in the early stages of formation, where nuclear fusion has not yet begun. A white dwarf is a small, dense star that is the remnant core of a low to medium mass star after it has exhausted its nuclear fuel.

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 bigger than a main sequence?
No, a white dwarf is generally smaller than a main sequence star because it is the remnant core of a star that has exhausted its nuclear fuel and collapsed. Main sequence stars are actively undergoing nuclear fusion and are typically larger in size.
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.
