evolution of stars

what are nebulas

cloud of dust and gas

how is protostar formed

gravity pulls dust and gas together, temperature increase due to more particles collide.

how is main sequence star made

when the pressure and gravity are balanced out

how are red giant or red supergiant made

when hydrogen runs out, making an imbalance force of the pressure and gravity making planet smaller but hotter and denser. This creates energy that is greater than the gravitational pull making it expand. Red Gian forms by a small star. Red supergaint forms by a large star.

what does red giant lead to

white dwarf

how is white dwarf formed

when there is imbalance forces, resulting to eject its outer layer.

What does a red supergiant soon form

supernova

how is a supernova formed

when helium fuses together into iron. However iron cannot release any energy so there is an imbalance, gravity is greater than the pressure theevenutally it will explode.

what can a supernova lead to

neutron star and black hole

how is a neutron star formed

when the supernova explodes, the outer layers of the star eject. Leaving a dense core called a neutron star.

how is a black hole formed

when the large star gets crushed by the massive force of gravity
