Answer:
A massive star will leave the main sequence once its core hydrogen is depleted. After that time, it becomes a supergiant star, and it will begin fusing a variety of heavier elements as fusion thresholds are overcome. Then carbon fusion, neon fusion, oxygen fusion, and silicon fusion. After the inner core becomes iron, which requires energy to fuse, the star will experience a core collapse and create a neutron star from its core. The rest of the star explodes into a supernova. The evolution differs from a solar-mass star in several ways. First, the fusion history is different: A massive star can fuse more elements and create more fusion products. Second, the lifespan for each star is quite different, with a solar-mass star taking a much longer time for each stage of its evolution compared to the massive star. Third, the method by which each star loses mass is different, with a solar-mass star losing mass via the planetary nebula phase, while a massive star undergoes a supernova event. Finally, the final state of each star is different, with a low-mass star becoming a white dwarf, and a massive star becoming a neutron star. The main factor that determines the fate of each star and the path they will take to get to the fate is their initial mass on the main sequence.
The evolution of massive star occurs with fusion reaction more gradually rather than with a sudden flash.
Evolution of massive star?
Massive stars evolve in the same way that the Sun does but always more quickly due to the formation of a carbon-oxygen core. The stars shine steadily until the hydrogen has combine to form helium atom.
One difference between the massive star and sun formation is that stars with more than twice the mass of the Sun, helium begins fusion reaction more gradually rather than with a sudden flash.
