Production of Heavier Elements

What elements make up the star? How do these elements change as the star ages? How does nuclear fusion change over time as the star ages?
The elements that make up a star are hydrogen and helium. The core of a star changes which changes the temperature, the amount of light the star gives off and the size of the star. Nuclear fusion changes as the star ages by either stopping at a halt and not produce anymore or it continues to expand the star even bigger.
Where does the energy of light and heat comefrom?
From the core of the star. Some examples of fusion reactions specific to the different ages of a star are the supernova which is when a star explodes because it was too big or when a star becomes a white dwarf and stops producing energy waiting to eventually burn out.
