- One day Shiela and Andrew met and they had a small talk about the life cycle of the stars.
- Hi there Andrew! Do you want to hear a story about the stars?
- Yes, of course I would love to hear that.
- Stars are formed by a massive cloud of gas and dust. The amount of substance available in its nebula determines its mass.
- Yes, it is correct. Nuclear fusion happens in the cloud core when the temperature exceeds 15,000,000 degrees. After that, the cloud begins to glow brightly, contracts slightly, and stabilizes.
- The gas heats up and turns into a protostar as it spins faster.
- Is that a what they called protostar?
- It then moves on to a stage when the core temperature approaches the point where fusion can begin. Helium is created by converting hydrogen to helium. When hydrogen starts to run out and is no longer creating heat, the core compresses and becomes unstable.
- The star's outer shell, which is primarily comprised of hydrogen, begins to expand. After that, it cools down and turns red. The star has progressed to the stage of being a red giant.
- It will become a neutron star if the residue of the explosion is 1.4 to roughly 3 times the mass of our sun.
- Smaller stars become white dwarfs after a supernova explosion, and then cool down to become black dwarfs.
- The nuclear forces are overcome by gravity, preventing protons and neutrons from mixing. The core is thus suffocated by its own gravity.
- Don't metion it.
- After that, it will become a black hole.
- What a wonderful story about stars! Thank you for sharing!
