Can a white dwarf become a planet?
White dwarfs are thought to be the final evolutionary state of stars whose mass is not high enough to become a neutron star or black hole….Composition and structure.
| Material | Density in kg/m3 | Notes |
|---|---|---|
| Supermassive black hole | c. 1,000 | Critical density of a black hole of around 108 solar masses. |
What is the closest white dwarf star to Earth?
Sirius B
At 8.6 light-years away, Sirius B is the nearest known white dwarf star to Earth.
What would happen if you stood on a white dwarf?
A white dwarf is so dense that the only thing holding it up is electron degeneracy pressure. So while it might still be hot enough to be called a “plasma” you would not be able to sink into it. You would be converted into plasma and that plasma would merge with it, yes.
What happens to sun when it dies?
In five billion years, the sun is expected to expand, becoming what is known as a red giant. “In this process of the sun becoming a red giant, it’s likely going to obliterate the inner planets … Once the sun completely runs out fuel, it will contract into a cold corpse of a star – a white dwarf.
What would happen if you ate a star?
“You’d pop it into your mouth and it would fall unimpeded through your body, carve a channel through your gut, come out through your nether regions, and burrow a hole toward the center of the Earth,” Hammergren says.
Can a white dwarf star turn into a black hole?
A black hole is a hard no. A 2.5 (about) solar mass neutron star can turn into a black hole. A 1.4 solar mass white dwarf even if made from Iron, even if it somehow manages to collapse into a neutron star, it would be much too light to collapse into a black hole.
Can a white dwarf turn into a neutron star?
But is there any possibility that a white dwarf can turn into a neutron star (or possibly a black hole)? The answer is: to a neutron star – possibly; to a black hole, no.
Do white dwarfs explode in a supernova?
Not for most white dwarfs, because they are usually full of fusionable material (most notably carbon and oxygen). When material like that starts to undergo gravitational collapse, it heats up and fuses, creating the type Ia supernova and leaving nothing behind because of the intensity of the explosion.
