Describe the future of our Sun?

When all of the Sun's core supply of Hydrogen has been converted into Helium nuclear fusion will stop, gravity will crush the core smaller. The pressure and temperature becomes so great that Helium is converted into Carbon. A red giant is formed as the star color changes from the expanded gases. When all of the core supply of Helium is converted into Carbon, nuclear fusion stops and the core collapses and is now called a White dwarf.
