Can a dwarf star go supernova?

The most massive stars, with eight times the mass of the sun or more, will never become white dwarfs. Instead, at the end of their lives, white dwarfs will explode in a violent supernova, leaving behind a neutron star or black hole. Smaller stars, such as red dwarfs, don’t make it to the red giant state.

Can brown dwarf become white dwarf?

Astronomers believe in about 250 million years the brown dwarf will get so close that the white dwarf’s gravity will draw material from the brown dwarf and eventually flare up as the material just above its surface explodes.

Can a brown dwarf explode?

This suggests an unusual type of thermonuclear explosion. “We think that the brown dwarf will have disintegrated. Some of it burned up in the thermonuclear explosions that were triggered on the white dwarf, and some of it was thrown out.

Is Jupiter a dwarf star?

However Jupiter has the materials of a star it lacks the mass. It has to be a minimum 80 times more massive to even be a low mass star(red dwarf). The sun has 1000 masses of Jupiter and even it is only a medium mass star. So in a sense Jupiter is a failed star but not really.

Can a brown dwarf become a star if it has mass?

Brown dwarfs do not even have enough mass and fuel, hydrogen, to become a star. So, the answer is no. This is, of course, if they never siphon more energy from another brown dwarf to become a star that can go supernova.

How does a white dwarf become a supernova?

At some point the white has gained so much mass that it explodes in a type Ia supernova. There are brown dwarfs in binary systems, but the process that allows white dwarfs to become supernova does only work for white dwarfs.

What is the lowest mass companion for a Type Ia supernova?

So I think that is why the lowest mass companion for a type Ia supernova is a small white dwarf rather than a brown dwarf. A brown dwarf can of course spiral into a white dwarf, but unless the white dwarf is right at the limit, then it will just produce a nova rather than a supernova.

What is the nearest brown dwarf to the Sun?

The nearest known brown dwarfs are located in the Luhman 16 system, a binary of L and T type brown dwarfs at a distance of about 6.5 light years. Luhman 16 is the third closest system to the Sun after Alpha Centauri and Barnard’s Star . The smaller object is Gliese 229B, about 20 to 50 times the mass of Jupiter, orbiting the star Gliese 229.
