dailygalaxy. com dangthatscool. com Red Giant • Lifetime: 0. 1 - 2 billion years • Smallest kind of main sequence star. • No hydrogen left Ø core begins to contract ² releases gravitational energy • outer layers cool down • shrink and expand

dailygalaxy. com White Dwarf • Lifetime: 1015 - 1025 years • Evolution: dead, cooling • burned-out cores of collapsed stars • Planetary nebula

gstatic. com Brown Dwarf • Lifetime: unknown • Too small to generate heat Ø hasn't gotten enough mass ² Nuclear Fusion • very dim and cool

findpk. com Yellow Dwarf • Lifetime: 4 - 17 billion years • Sun • larger than majority of stars • Yellow dwarfs like the sun are white Ø Appears yellow through Rayleigh scattering

space. com Black Dwarf • Lifetime: unknown • Evolution: dead • white dwarf has cooled down Ø No longer emits light

deviantart. net Neutron Stars • Lifetime: unknown • Evolution: dead, cooling • core collapses Ø combines electrons with protons to form neutrons Ø Gravity forces core to become even smaller.

sunandstar. net Orange Dwarf • very common • Lifespan three times longer than yellow dwarfs

sunandstar. net Red Dwarf • most common type of star • Burn their fuel slowly Ø live a very long time Ø Not shine as brightly

static. memrise. com Blue Giant • large and compact • burn their fuel quickly Ø extremely bright • grow larger and explode Ø Super nova

apod. nasa. gov Red Super Giant • more than 8 to 10 solar masses • Outer hydrogen and helium is inactive. • Below hydrogen fuse to helium. • Next helium fuse to carbon. • core iron • shines extremely bright, short time
