What are 6 stages of how a star forms?

Stage 1-Giant Molecular Cloud: A star forms as a massive gas cloud, which then contracts due to gravity as a region of high density within the cloud condenses into a massive globule of gas and dust.

Stage 2-Protostar: Over a period of approximately 10 million years, a region of condensing matter begins to heat up and glow, giving rise to protostars.

Stage 3 - T Tauri stage: The forming star becomes visible when it starts to produce strong stellar winds that push away the surrounding gas and molecules.

Stage 4: Nuclear Fusion: When the protostar's core temperature reaches 15 million degrees Kelvin, which is reached when sufficient matter is present, nuclear reactions can begin, allowing hydrogen to fuse with helium to form helium.

Stages 5 and 6: Main sequence star: The star spends 90% of its life in this stage, fusing hydrogen to form helium in its core. The star reaches hydrostatic equilibrium, in which its gravity compression is balanced by its outward pressure, giving it a solid shape. The star starts to release energy, stopping it from contracting even more and causing it to shine.

1. Molecular Cloud: A cloud of gas and dust in space starts to collapse due to gravity. 2. Protostar: The collapsing material forms a dense core surrounded by a rotating disk. Heat and pressure increase at the core. 3. Main Sequence: Nuclear fusion begins in the core, leading to the formation of a stable star. In the star's core, hydrogen fuses into helium. 4. Red Giant or Supergiant: As the star ages, it expands and cools, turning it into a red giant or supergiant. 5. Planetary Nebula or Supernova: Depending on the star's mass, it will either shed its outer layers to form a planetary nebula or explode as a supernova. 6. White Dwarf or Neutron Star or Black Hole: The star's core remains, forming a white dwarf if it's low mass, a neutron star if it's medium mass.
