life cycle of stars:STARS SIZE OF THE SUN

stars are formed from cloud of dust-a nebula

gravity makes the dust spiral together-a protostar

gravitational attraction highers density which highers particle collision which increases temp

hydrogen nuclei do nuclear fusion to turn to helium nuclei which releases a lot of energy

stars that enter a long stable period-main sequence star

equilibrium made by outward pressure of nuclear fusion and the pulling in of gravity

this lasts several billion years

hydrogen runs out

heavier elements up to iron are created in the core

stars produce all naturally occuring…
