what types of main sequence stars supernovas
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.
