36Life cycle of the stars.
The diagram below shows the possible life cycle for stars of different masses. SM stands
for Solar Masses. If a star is 3SM then it is 3 times the mass of the Sun.
Gravitational collapse of cloud
of dust and gas (nebula).

hydrogen.
Planetary nebula
Supernova explosion.
Elements heavier than
lead are formed.
Black hole.
White dwarf
Stars greater than 25 SM.
Neutron star
Brown dwarfs are failed stars that never have enough mass in order to get hot enough to
achieve nuclear fusion.
Red dwarf stars: these are low mass stars that do achieve nuclear fusion. They are not
very bright and have long lifetimes. They are main sequence stars.
