Star Facts

Types of Stars and How They Form Low Mass Stars Medium Mass Stars High Mass Stars

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

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

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

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

Stars

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.

Electromagnetic Radiation Energy that travels through space in waves Stars give off electromagnetic radiation in different forms Each form has its own wavelength Radio Waves Infrared Rays Visible Light Ultraviolet Light X-Rays Gamma Rays
