4. Low Mass Stars Nebula Protostar Main Sequence Star White Dwarf
Small, cool stars
Use hydrogen slowly
Live more than 30 billion of year

5. Medium Mass Stars Nebula Protostar Main Sequence Star Red Giant
Planetary Nebula
White Dwarf
Medium size and temperature
Live about 10 billion years

6. High Mass Stars Nebula Photostar Main Sequence Star Supergiant
Supernova
Neutron Star or Black Hole
Hottest, most massive stars
Shortest lives: millions of years
Uses hydrogen quickly

7. Black Holes
Formed when a supernova explodes causing its core to collapse.
So dense that even light can’t escape its gravity.

8. Stars

9. Starlight Brightness
Apparent Magnitude: How bright a star appears to be from earth when viewed with the unaided eye. Distance can cause a dimmer star to appear to be brighter than a brighter star that is farther away.
Absolute Magnitude: The amount of light (brightness) a star actually has. This is an actual measurement.
