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.

Why don't you need to worry about your sun becomming a supernova?
Our sun does not have enough mass to undergo a supernova event. The sun is classified as a small to medium-sized star, and it will eventually evolve into a red giant and then a white dwarf over billions of years, but it is not massive enough to explode in a supernova.
What is a Chandrasekhar mass and how does it relate to a supernova?
A Chandrasekhar mass is the maximum mass limit (about 1.4 times the mass of the Sun) that a white dwarf star can have before it collapses under its own gravity and triggers a supernova explosion. When a white dwarf accretes matter from a companion star or merges with another white dwarf, exceeding the Chandrasekhar mass, it can collapse and explode as a Type Ia supernova.
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 kind of star is most likely to become a white-dwarf supernova?
A white dwarf supernova occurs when a white dwarf in a binary system accretes matter from its companion star, surpassing its Chandrasekhar limit. This type of supernova is not usually associated with a specific type of star, but with the evolutionary path of the white dwarf in a binary system.
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.
What is the order from smallest to largest sun supernova red giant white dwarf?
White Dwarf, Sun, Red Giant, Supernova

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 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.
Can a star less massive then the sun become a supernova?
No, stars less massive than the Sun do not have enough mass to undergo a supernova explosion. Instead, they may end their lives as a white dwarf or, if they are even less massive, a planetary nebula. Supernovae are events associated with more massive stars.
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.
What do you think the difference is between a black dwarf and a supernova explosion?
A black dwarf is a dead white dwarf. By dead, I mean a star that no longer burns. A white dwarf, in turn, is a dead "moderate" star (a star like our sun). So a black dwarf is a star that's died twice, with mass not much higher or probably lower than that of our sun. A supernova, is the "death" of a star that's really huge. By huge, I mean it has a mass that's considerably higher than that of our sun. That kind of star doesn't turn into a white dwarf. Rather, it becomes either a neutron star (pulsar or non-pulsar) or a black hole.
