Hydrogen and Helium, with the former decreasing and the latter increasing. Rigel is fusing H into He at a prodigious rate and in a million years or so will start to collapse as its fuel runs out.
Supernova
Supernova
A black hole or a neutron star, depending on the mass of the remaining core. Also a lot of material is ejected into space.
A star with an iron core is typically a red supergiant star that has exhausted its nuclear fuel and is in the final stages of its life cycle. The iron core forms when the star's fusion processes can no longer generate enough energy to counteract gravitational collapse, leading to a supernova explosion.
What the core of the star will become is dependent of the mass of the supergiant star. Stars between about 3 and 10 solar masses will generally become neutron stars. Stars above 10 solar masses generally become black holes.

A giant star is a dying star that expanded, and the core shrinks are the same time. When the shell of the giant star drift into space as planetary nebula, the core became a white dwarf. The white dwarf is made from the core of the giant star.

the core of the sun is a seething nuclear furnace where millions of tons of hydrogen are being fused in to helium every second.
The rest of the star expands.

A stars core is made up of mostly hydrogen. If you want the real numbers it is: 73% hydrogen, 25% helium, and the last 2% is all the other elements of the period table.
Temperatures in the star's core can reach 3x109 K.
A star's core consists mostly of hydrogen. As the star ages, the amount of helium, carbon and other elements in the core increases as they are the result "ash" resulting from the consumption of the hydrogen fuel.
