Big huge stars
Such a star is called a red giant.
A star is considered "dead" when nuclear fusion stops in its core. The name of the a star before this happens depends on its size. If its a star the size of our own, Sol, then it will be called a red giant. If it is considerably lager then it will be called either a giant, bright giant, super giant or hyper giant. This again depends on its size.
