Question

If a white dwarf gains sufficient mass, what could it can become ?

Answer 1

once it becomes a whie dwarf it just burns out slowly over time into nothing, though i am not quite sure if it turns into another cluster which forms a star again idk

Answer 2

The problem is that once a red giant blows off its outer layers (leaving only the white dwarf) the solar system in question will be so completely obliterated that nothing nearby can be pulled in enough to change its mass.  And even if it passed near another star, since most stars are main sequence, the white dwarf itself would be pulled in.

Answer 3

If a White Dwarf steals material from a companion star, at a certain limit, it will explode.  They're called Carbon Bombs or Carbon Detonations, I can't remember.  It's something like that.  It's one of the kinds of Supernova, and one of the most common, in fact.  What's left is nothing at all.  It's useful, because the limit is constant, and you can determine by its redshift how far away distant galaxies are.

Answer 4

If a white dwarf orbits around a larger "normal" star in what's known as a binary star system, the white dwarf can draw off material from the other star. This material falls onto the surface of the white dwarf and once it reaches a certain level will explode in a Type 1A supernova.

Answer 5

If it gains enough mass it will collapse into a neutron star.

Answer 6

There are cases known where white dwarfs are located in binary systems in which material falls from the other star onto the white dwarf.  This generally causes the white dwarf to become a recurrent nova, although there are other possibilities depending upon the amount of mass deposited and the rate of transfer of the mass, as well as the exact mix of elements transferred, which in turn depends upon the mass and age of the companion star.
