Nothing is known about any companion star. There is a "Nemesis hypothesis", according to which there could be one, but no companion has been confirmed.
When a white dwarf star accretes hydrogen from a companion star, it can trigger a runaway nuclear fusion reaction that causes a sudden and bright increase in brightness called a nova. This explosion is not as powerful as a supernova, and the white dwarf usually survives to potentially experience multiple nova events.
It is possible that the Sun had a companion star, and that the two became separated due to interactions of other nearby stars.
No. Nor does any other star, unless there is an unknown companion to our Sun, like the hypothetical "Nemesis".No. Nor does any other star, unless there is an unknown companion to our Sun, like the hypothetical "Nemesis".No. Nor does any other star, unless there is an unknown companion to our Sun, like the hypothetical "Nemesis".No. Nor does any other star, unless there is an unknown companion to our Sun, like the hypothetical "Nemesis".
big explosion :O the sun is too small a star for a supernova.
If the sun were to undergo a nova event, it would expel its outer layers into space, creating a bright explosion. This would not result in the complete destruction of the sun, but it would significantly alter its appearance and affect the surrounding planets in the solar system.
The explosion of a dwarf star is called a nova or a supernova, depending on the type of dwarf star and the circumstances of the explosion. Novas are less powerful explosions caused by a white dwarf siphoning material from a companion star, while supernovas are much more energetic explosions that can occur in white dwarfs or other types of stars.
Very low. Such a companion would have been detected by now, even if only through its gravitational effects.
This hypothesis was proposed by Lyttleon in 1938. Before the formation of planets, the sun had a companion star. Another star approached close to these double stars and dragged the companion star away. A gaseous filament was torn from the companion star and it remained close to the sun.The planets were originated from this gaseous filament in the same way as described in the gaseous tidal hypothesis.

A type-1 supernova is produced by the explosion of a white dwarf star in a binary system. This occurs when the white dwarf accretes material from its companion star, triggering a runaway nuclear fusion reaction that results in a sudden and catastrophic explosion.
The stage missing in the chart is the supernova explosion. When a star ten times more massive than the sun reaches the end of its life cycle, it undergoes a supernova explosion, where the star's core collapses and then rebounds outward in a powerful explosion, leaving behind either a neutron star or a black hole.
For a star that is 10x or more the size of our sun? Supernova explosion, followed by the implosion of the star, forming a neutron star. For a star that is 50x or more the size of our sun? Supernova explosion followed by the implosion of the star, crushing down extremely small, forming a black hole. For a star that is 100x or more the size of our sun? Supernova explosion followed by the implosion of the star, crushing down extremely small, forming a supermassive black hole
