white drawf
A dead star with the density of an atomic nuclei is called a neutron star. Neutron stars are incredibly dense and are composed mostly of tightly packed neutrons. They form when massive stars explode in a supernova and their cores collapse under gravity.
A massive collapsed star is a dead star.
A white dwarf is not considered a "dead star." It is considered a dying star, but not dead yet. A white dwarf is at its smallest state and could become a supernova when its center runs out of fuel to burn.
Arcturus is hot. Bear in mind that only a hot star is even going to be seen in the night sky. Any cold star would also be dark.
A small dead star is typically a white dwarf, which is the leftover core of a star that was not massive enough to become a supernova. White dwarfs are very dense, about the size of Earth but with the mass of a star.
It is called a Black Dwarf
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.

cold war or cold war amercia
it was a hot war was but it was called the ( COLD WAR) probably cause all the dead bodies.
No. The remnants left behind by dead stars retain a lot of left-over heat and will take a long time to cool down. Currently the universe has not been around long enough for any dead star to have cooled to a temperature we might consider cold.
When it has burned out all it's "fuel" - combustibles gases, it's just a burnt out black dead husk.
Th cold war
Star wars in the cold war was a satellite Ronald Reagan had set up in space to find missiles before they got to America and shoot them down over the ocean. Reagan called his program the Strategic Defense Initiative. Critics who didn't like the idea or Ronald Reagan mockingly called it "Star wars."
No. There is no such thing a a cold star. Sirius consists of two stars, both of which are hotter than the average star.
