It already has. Sirius B is a white dwarf, the dense remnant of a dead star. While it is no longer producing energy through fusion, Sirius B still glows with the leftover heat of when it was an active star. Because of the huge amount of heat and relatively small surface area, it will take trillions of years for Sirius B to cool.
Sirius is a binary star system Sirius A and Sirius B.The distance separating Sirius A from B varies between 8.1 and 31.5 AU. (See related question).
Sirius BSirius B has a radii of 0.0084 solar radii.Barnard's star has a radii of 0.196 solar radii.
Sirius B is a white dwarf, meaning it is already the remnant of a dead star. That star died about 120 million years ago.
Sirius is actually a binary star system. Sirius A has an apparent magnitude of -1.46 whereas Sirius B has an apparent magnitude of 8.3
Yes. Sirius actually consists of two stars. The main object, Sirius A is not only bigger than Earth but is almost twice the diameter of the sun. The secondary star, Sirius B is a collapsed remnant of a star called a white dwarf. It is slightly smaller than Earth but far denser.
No. Sirius B is a white dwarf. It is the remnant of a star that used up its supply of hydrogen.

It is not real. Sirius is a two-star system containing only Sirius A and Sirius B.
Sirius's fate might be peaceful; just ejecting it's outer red giant layers to make a planetary nebula. It is 2.02 times the mass of the Sun. However, Sirius has a white dwarf companion. On Sirius B's death, Sirius A might have formed. At the other end, Sirius B might destroy Sirius A. White dwarfs have very strong gravity, and if it is close enough, Sirius B might steal material from Sirius A. When a white dwarf stealing mass from the parent star has enough mass to create iron, the iron triggers a Type 1a supernova. If this happens to Sirius B, Sirius A could either be destroyed by the immense force of the explosion, or become a runaway star, travelling faster than even Barnard's Star. If this is the case, Sirius A might eat smaller stars or crash and burn into a larger star. If it heads towards us if this happens, we would be doomed.

Sure - the two attract each other. In the case of a double star - as Sirius A and Sirius B - both revolve around their common center of mass.

Sirius B is a white dwarf. So it is low mass compared to other stellar remnants.
