Detailed explanation-1: -protostar, main-sequence, white dwarf, red giant.
Detailed explanation-2: -The exact stages of evolutions are: Subgiant Branch (SGB)-hydrogen shell burning-outer layers swell. Red Giant Branch-helium ash core compresses-increased hydrogen shell burning. First Dredge Up-expanding atmosphere cools star-stirs carbon, nitrogen and oxygen upward-star heats up.
Detailed explanation-3: -The stages of a low massive stars from the earliest to the latest are: Protostar Main sequence First red giant phase Helium flash Second red giant phase.
Detailed explanation-4: -Low mass stars live a long time, fusing all their hydrogen into helium over a trillion years. More massive stars like the Sun live shorter lives. They fuse hydrogen into helium, and eventually helium into carbon. When this happens they expand, get brighter, and cool off, becoming red giants.
Detailed explanation-5: -protostar, main-sequence, white dwarf, red giant.
Detailed explanation-6: -Step Four (White Dwarf) All that would be left is the carbon core. Life Cycle of a High Mass Star. Step Two (Red Giant) Step One (Birth in the Stellar Nebulae) Step One (Main Sequence) Step Two (Protostar) Step Four (Neutron Star/Black Hole) Step Three (Supernova) More items
