All the stars use fusion/fission reaction to generate energy and light. When whole of the fuels is consumed it becomes "Dead". Now it can't emit radiations/heat/light etc. Its mass is supposed to be concentrated at the center and the density is increased,,, hence force of gravitation is increased. Any object near to it is strongly attracted towards its center and now it is called "Black Hole".

a star which is about is end its life time (from protostar to the ending stage) and become a black hole or a black dwarf (stage after white dwarf) is called a dying star.
To understand the chemistry and physics of stardeath, researchers researchers study stellar winds at varying distances out from dying stars. The chemical transformations they unravel helps them piece together the dying process.
During most of a star's lifetime, nuclear fusion in the core generates enough outward pressure to exactly balance the inward pull of gravity associated with the star's mass. As the nuclear fuel is exhausted, the outward forces diminish, allowing the gravitation to compress the star inward. Eventually, all possible nuclear fuel is used up and the core collapses.

A dying star is one that has exhausted its hydrogen stores and cannot continue to produce nuclear reactions. If the star has enough mass, it will end its days with a last spectacular explosion and then shrink back to a brown dwarf or if it has enough mass left it can become a pulsar or a neuron star.

After most stars consume their hydrogen fuel supply they super nova (explode), this is the main source of elements in the universe (star dust). Some stars fates's are less dramatic depending on their size.

all stars have a life-cycle, when they die typically one of two things can happen (depending on the structure of the star, density, mass etc) it can either collape in on it's self and become a black hole or explode in a super-nova :D

a nova.
it happens when the fuel [ mostly hydrogen] is more or less consumed and the star can no more generate sufficient energy.
