What are the 6 stages of a star?
Formation of Stars Like the Sun
- STAGE 1: AN INTERSTELLAR CLOUD.
- STAGE 2: A COLLAPSING CLOUD FRAGMENT.
- STAGE 3: FRAGMENTATION CEASES.
- STAGE 4: A PROTOSTAR.
- STAGE 5: PROTOSTELLAR EVOLUTION.
- STAGE 6: A NEWBORN STAR.
- STAGE 7: THE MAIN SEQUENCE AT LAST.
What are the 5 stages of an average star?
The formation and life cycle of stars
- A nebula. A star forms from massive clouds of dust and gas in space, also known as a nebula.
- Protostar. As the mass falls together it gets hot.
- Main sequence star.
- Red giant star.
- White dwarf.
- Supernova.
- Neutron star or black hole.
What are the stages in the life cycle of a massive star?
Any star which is larger than eight solar masses during its regular main sequence lifetime is considered a massive star. They typically have a quick main sequence phase, a short red supergiant phase, and a spectacular death via a supernova explosion.
What is the sixth stage of a star’s life?
Stage 6 – The helium core now starts to contract further and reactions begin to occur in a shell around the core. Stage 7 – The core is hot enough for the helium to fuse to form carbon. The outer layers begin to expand, cool and shine less brightly. The expanding star is now called a Red Giant.
What are the three end stages of stars?
Three end stages of stars are:
- White Dwarf.
- Neutrons Star.
- Black Hole.
What is the fourth stage in the life cycle of an average star?
Stage 4 – The core collapses in less than a second, causing an explosion called a Supernova, in which a shock wave blows of the outer layers of the star. (The actual supernova shines brighter than the entire galaxy for a short time).
What is the second step of star life cycle?
Step 1 – Green – A cloud of gas and dust collapses due to gravity, creating a protostar. Step 2 – Blue – Gravitational energy powers the young star until… Step 3 – Yellow – … nuclear fusion occurs.
