Revealing Star ! (In a concise manner)
Star are a very important component of our universe. To start with we assume there is a stellar nebula (a big gas cloud) and due to gravity of this cloud it collapses into a star there are generally two types of star viz. average star and massive star. Due to this high compression of the gas molecules there is nuclear fission chain reaction which will slowly combine and release massive amount of nuclear energy. Generally a small star can produce helium nuclei and a very big star can produce the last stable nuclei(Z=26,Iron Nuclei ) according to binding energy graph. But during this process there are several steps. The next stage starts after the completion of preliminary hydrogen fuel in the formation of light helium nuclei and other products, once the fuel is completed the energy releasing suddenly stops and the red giant is formed but now depending on the mass of star it will have two options one(formation of planetary nebulae and finally white dwarf ->lighter stars) and second(
