Life Cycle Of A Star
By Aaron Le
Star Life Cycle and Human Life Cycle
1. Early Stage/Developmental Stage: Protostar and Fetus
2. Learning Stage: Main Sequence and Infancy Through Childhood
3. Working Stage: Red Giant/Super Giant and Middle Age
4. Retire/Death Stage: White Dwarf/Black Hole and Old Age-Death
Protostar: This stage primarily consists of hydrogen and a little helium. It will begin hydrogen fusion when it turns into a main sequence star.Equilibrium: This is a star's main goal, stability between gas pressure pushing out from center and gravity pulling in towards center.
Main Sequence: Fusing hydrogen atoms into helium atoms is what happens during this stage. The lifespan is determined by the size of the star. After the main sequence, the processes could either stop due to no hydrogen or substitute helium in rather than hydrogen.Fusion: Two things conjoining together to make something bigger.
Red Giant/Super Giant
White Dwarf/Black Hole/Death
Supernova: Massive stars that don't turn into white dwarfs end up as a violent supernova explosion.
Planetary Nebula: Lower-medium stars that shed their outer layers into rings known as the planetary nebula.
Red and Blue Shifts: When objects in space such as stars or galaxies move closer or further away. Further away results in a red shift while closer results in a blue shift.
Doppler Effect: A star's light also emanates in wavelengths, this means that the wave can crush together or stretch apart depending on relative location of the object.
Origins of the Elements
Hydrogen: Born from the Big Bang.
Helium: Fuses into Nitrogen and Oxygen from Hydrogen.
Iron: Silicon fuses with other things to make things such as iron or heavier than it.
