Life cycle of stars

The stars can be compared to a person. They can be young and old. Our sun is a young star that is still going through the "growing up" stage.

Now we are going to discover how many types of cycles stars have in their lifespan.

1. Baby star

At the beginning, everything starts with the large gas cloud. Additionally, the other aspect that plays a vital role in the formation of the star is temperature. The temperature must be low.

However, the speed of star formation will also depend on its size. It is believed that stars with a diameter of the Sun have enough energy to exist comfortably for about 10 billion years. Now we are going to the next stage of a star's formation

2. Protostar

The protostar stage is the earliest one in the process of stellar evolution. At this stage the star is still gathering mass from its parent. Protostars are warmer than other materials in the molecular cloud so they can be seen with infrared vision. Several protostars can exist in one molecular cloud. It depends on the size of the cloud.

3. T-Tauri Phase.

A young star starts to form in the T-Tauri phase, and it begins to produce strong winds that push away the surrounding molecule and gas. Furthermore, this stage makes stars visible to people.

4. Main sequence star

This is one of the most important stages in a star's life. It spends 90% of its life in this stage, fusing with hydrogen molecules and forming helium. Most noteworthy, the sun is currently in this stage.

5. Expansion into Red Giant

Our sun will become a red giant in about five billion years. When all the hydrogen is converted into helium, the core will collapse on itself which will cause the star to expand.

It is cooler than the main-sequence star, and that’s why it appears red and it can become large enough to be a supergiant.

6. The fusion of Heavier Elements

Nuclear fusion is the process by which nuclear reactions between light elements form heavier elements. When an expanding star begins to fuse with helium molecules in its core, this reaction prevents the core from collapsing. After helium fusion ends, the core shrinks, and stars start fusing carbon.

7. Supernovae and Planetary Nebulae

Supernova explosion is the biggest event in the universe. Furthermore, most of the material is dispersed, but the core implodes rapidly into a neutron star or a singularity known as a black hole.
