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.
A giant star would experience a supernova explosion, in order to become a white dwarf.
A type-I supernova occurs when a white dwarf star accumulates mass from a companion star until it reaches a critical threshold, triggering a runaway nuclear fusion reaction. This causes the white dwarf to explode in a bright supernova event.
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.
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.
No, Sirius will not become a supernova. It is a relatively young star compared to those that typically go supernova, and its mass is not sufficient to trigger such an explosive event. Sirius is expected to eventually evolve into a white dwarf.

White Dwarf.
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.

No. It's a white dwarf, meaning that it has no more fuel left for such things.
No, Sirius will not become a supernova. It is a relatively young star compared to those that typically go supernova, and its mass is not sufficient to trigger such an explosive event. Sirius is expected to eventually evolve into 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.
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.
