This paper summarises the process of stellar formation and evolution of stars over time and how other processes within the general phenomenon affect the dynamics of the life of active stars such as neutron stars, black holes, magnetars, and pulsars. Main sequence life has also been looked into while comparing the properties of these active stars with the ones of main sequence stars to see how much their dynamics differ over time. From multiple different sources, this paper has been able to give us an insight into the workings of stars and how the initial states of matter can affect the courses of life of the infinitesimal quantity of stars in the universe.
