Question:Can you summarise the stages of a stars 'life-cycle'?
Summary of 'life-cycle' of a star.
Early life history of a star:
1.Interstellar gas cloud (a Nebula)
2.Gravitational collapse producing a proto-star
4.Long period of normal life (main sequence)
5.End depends on mass of star.
End of the 'life-cycle' of a small star:
End of the 'life-cycle' of a large star:
8.Neutron star or black hole (for massive stars).
NB A small star has less than 3 times the mass of the Sun.
