Planetary Nebula

Supernova

Black Hole

Neutron Star

If part of the original star remains, the intense pressure in the inside of the supergiant causes the electrons and the protons to combine. Leaving the star a big ball of neutrons.

Because black holes are so dense, nothing can escape the gravity. Not even light.

Since the inward and outward pull of the star is equal, the star is stable. The electrons inside repel eachother creating the outward pull.

The star now sheds its outer layers and diffuse into a planetary nebula. Later, it will only have 20% of its original mass.

The temperature rises to 100 bllion degrees as the iron atoms crush together. The force of the iron nuclei beats the pravitational force, causing an "explosive shock wave." Then, the shock sends the materiel away from the star.

Once the supply of hydrogen runs out, the star begind to "swell" and the temperature and the pressure rises. This heat counteracts as the outward force.H-R Diagram location: Red Giant

Gravity trys to pull the star inward while the pressure from the fusion inside prsses outward giveing th star balance. H-R Diagram location:Main Sequence

After the outer layers have swollen, the gravitational force begins to take over and the star begins to shrink. Then, the temperature and dense rises, causing nuclear reactions. Which temporarily stop the core from collapsing. H-R Diagram location: Super Giants

Gravity pulls together gas and dust, the temperature and pressure rises eventually creating a star
