Type I Supernovae. Stars, like our Sun, spend most of their lives on what is known as the main sequence. The main sequence begins when the star initially forms -- igniting nuclear fusion in its core -- and ends once the star has exhausted the hydrogen needed to sustain fusion and begins fusing heavier elements.Once a star leaves the main sequence it will follow a particular path that depends on its mass.For type I supernovae, we are concerned with stars that are no more than about 1.4 times the mass of our Sun.These stars, like our Sun, will leave the main sequence and go through several phases as it fuses elements up to Carbon.nce a star leaves the main sequence it will follow a particular path that depends on its mass. For type I supernovae, we are concerned with stars that are no more than about 1.4 times the mass of our Sun.
In our case, when a massive star is days away from a supernova explosion, it is composed of a lot of different things, from hydrogen at the very outer layers to iron at its very core. Most stars that are eight or more times the mass of our sun die as a Type II Supernova.he first is a supernova explosion that results from the collapse of a white dwarf, termed a Type Ia Supernova. A white dwarf is a remnant of a star that wasn't massive enough to force the ignition of carbon fusion for energy.
