Most likely it would be a "white dwarf". They are composed mainly of carbon and oxygen in an extremely dense form, called "electron degenerate matter".
Yes, that is correct. Elliptical galaxies are characterized by their elliptical or egg-shaped appearance and lack spiral arms of interstellar gas and dust. Unlike spiral galaxies, which have a flattened disk shape with spiral arms, elliptical galaxies have a more rounded or elongated shape. They are composed mainly of older stars and contain little to no ongoing star formation. Elliptical galaxies also tend to have less interstellar gas and dust compared to spiral galaxies.
