When a star has no fuel left and its outer layers escape into space what is its remaining core called?
When the layers escape into space, this is classified as a planetary nebula. What usually is left behind is a white dwarf.
What is the small dead star?
A small dead star is typically a white dwarf, which is the leftover core of a star that was not massive enough to become a supernova. White dwarfs are very dense, about the size of Earth but with the mass of a star.
What is an old dense hot star?
White dwarf
What is the maximum size of a white dwarf?
The maximum size of a white dwarf is about 1.4 times the mass of the Sun, known as the Chandrasekhar limit. If a white dwarf exceeds this limit, it can collapse further and ignite as a supernova.
When a white dwarf exceeds the Chandrasekhar limit what happens?
When a white dwarf exceeds the Chandrasekhar limit of about 1.4 times the mass of the Sun, electron degeneracy pressure is no longer able to support the star against gravity. This leads to the collapse of the white dwarf, resulting in a supernova explosion.
What is the term for the very dense white dwarf star that is left behind after a supernova?
Neutron Star
What is the term for tiny very dense white dwarf star that is left behind a supernova?
Neutron Star
What is the term for the tiny very dense white dwarf star that is left behind a supernova?
Neutron Star
What kind of star is most likely to become a white-dwarf supernova?
A supernova is a star that has exploded into dust and gas. A white-dwarf is a small, hot, dense star nearing the end of its life, that did not have enough mass to go supernova. So the answer is "none".
Is your sun a supernova or a white dwarf?
Our Sun is currently a main sequence star. It is not a supernova, as supernovae are massive explosions that occur at the end of a star's life cycle, and it is not a white dwarf, which is a type of star that has exhausted its nuclear fuel and collapsed to a very dense state.
What is the order from smallest to largest sun supernova red giant white dwarf?
White Dwarf, Sun, Red Giant, Supernova

What is the small dead star?
A small dead star is typically a white dwarf, which is the leftover core of a star that was not massive enough to become a supernova. White dwarfs are very dense, about the size of Earth but with the mass of a star.
What is the phase of a star approaches supernova?
White Dwarf.
What causes a white dwarf supernova?
A white dwarf supernova occurs when a white dwarf star in a binary system accretes material from a companion star, causing it to exceed the Chandrasekhar limit (1.4 solar masses). The core then undergoes a runaway nuclear fusion reaction, leading to a catastrophic explosion that destroys the white dwarf.
Will the sun become a supernova or black hole?
No. When the sun dies it will expel its outer layers in a series of gradual pulses and leave behind a white dwarf.
What happens with the white dwarf in a type 1a supernova?
The white dwarf collapses under its own gravity. This starts very rapid nuclear fusion reactions. It explodes as a supernova and "stuff" is scattered into space. Essentially nothing of the white dwarf, as an object, remains.
