Red giant • A Red giant is a big giant star of low mass in a phase of stellar evolution. • The sun will turn into a red giant in about four billions years. • Red giant forms when a star runs out of hydrogen fuel. • The Red giant is made out of many protons and elements such carbon. • Might end up a neutron star or a black hole depending on the mass they are born with.
Neutron star • Neutron stars are stars that collapsed under gravity. • Made of neutrons • Forms during super nova explosions of massive stars. • Forms from core of collapsing star condensing the core into a sphere. • Forms if a Red Giant has high mass.
White Dwarf • White dwarfs are remains of a star that collapsed. • Consists of electron degenerated matter. • Form from collapse of stellar cores in which nuclear fusion has stopped. • Consist of carbon and oxygen. • The Red giant is able to turn into a white dwarf if it has low mass.
Sun’s death • The sun is about 4.5 billions years old. In about 5 more billion years the sun will die. As the sun runs out of hydrogen and helium the sun will get bigger and slowly turn into a red giant. Once it is a red giant it will slowly shrink in diameter and turn into a white dwarf. Once it cools off even more it will turn into a Black Dwarf or a dead star.
