When it turns into a black dwarf neutron star or black hole.
Technically a dead star is when a star no longer undergoes nuclear fusion. Depending on the mass of the original star this will either be a white dwarf, neutron star or black hole. These are called stellar remnants.
A dead star. The dead star's smashed atoms come together, and are crushed again. This births a black hole
A dead star would basically be one that ran out of fuel. Such a star no longer has the radiation pressure to keep it "blown up"; it will collapse. Depending on its mass, it will collapse into a white dwarf, a neutron star, or a black hole.
The star is made of compact gasses, so compact that is shines enough to create a new star.
The general category is known as a dead star. There are three kinds of dead stars: 1. a white dwarf, which oddly enough by its description does not seem to be a dead star - "a dim very hot star" 2. a neutron star (viewed as a typical pulsar close to a normal star, but emitting x-rays); or 3. A black hole. The smallest and least dense stars become white dwarfs and the biggest, densest stars become black holes.
A massive collapsed star is a dead star.
A dull star
A dead star is one that no longer experiences nuclear fusion. This happens when a star runs out of hydrogen it can use to convert to helium.
it is result of a dead star
neutron star
Yes Umaga is dead.

It is not existing
black dwarf
Yes
no he isn't dead
It was a "fake dead reggae star" hoax
