From start to finish list each stage of the life cycle of a high mass star

Stage 1

The star contains two gases - hydrogen and helium. During the initial phase of the life cycle of a mass star, the hydrogen in the core burns until only helium is left.

Stage 2

When hydrogen transport is only in the context, the core becomes unstable with contracts. The lack of hydrogen causes helium to be absorbed into carbon. When the helium is gone, the composite carbon builds up heavy metals in the center such as iron, magnesium, neon and sulfur. The context will be iron and will stop burning. Then the outer shell of the star,

Stage 3

Over the next several million years or so, a series of nuclear reactions have emerged, creating unique substances in the shells around the metal core.

Stage 4

The core will then dissolve in less than a second, causing an explosion known as a supernova. The explosion will create a wave that blasts the outer layers.

Stage 5

If the context survives in supernovas, it can be a neutron star or a black hole. That depends on how many solar bases there are. Solar mass is the most common way to describe the mass of stars (One solar mass equals the mass of the Sun, or about 1.98892 × 10 ^ 30 kg). If you are between 1.5 and 3 thousand, you will be the smallest and darkest star. If it is greater than 3, then the contractor will complain of a black hole.
