What are the 5 life stages of a star?
What are the 5 life stages of a star?
All stars, irrespective of their size, follow the same 7 stage cycle, they start as a gas cloud and end as a star remnant.
- Giant Gas Cloud. A star originates from a large cloud of gas.
- Protostar.
- T-Tauri Phase.
- Main Sequence.
- Red Giant.
- The Fusion of Heavier Elements.
- Supernovae and Planetary Nebulae.
What are the 7 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 stages of a 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.
What are the stages to the life and death of a star?
stars spend most of their lives on the main sequence fusing hydrogen gas to helium gas. stars eventually swell up to form a red giant star. stars like the Sun end their lives as planetary nebulae and white dwarfs.
What are the stages of the star How did a star form?
Stage 1- Stars are born in a region of high density Nebula, and condenses into a huge globule of gas and dust and contracts under its own gravity. This image shows the Orion Nebula or M42 . Stage 2 – A region of condensing matter will begin to heat up and start to glow forming Protostars.
What is the first stage of a star?
protostar
A protostar is the earliest stage of a star’s life. A star is born when the gas and dust from a nebula become so hot that nuclear fusion starts.
What are the 10 stages of a 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 is the first stage of a star’s life cycle?
The gas in the nebula begins to glow. This is the first step in the life cycle of a star. It is called a protostar. This chemical change gives off a large amount of energy in the form of heat.
What is a first stage of a star life?
What’s the life of a star?
A star like our sun lives for about 10 billion years, while a star which weighs 20 times as much lives only 10 million years, about a thousandth as long.
What is the first stage of a stars life?
The gas in the nebula begins to glow. This is the first step in the life cycle of a star. It is called a protostar. This chemical change gives off a large amount of energy in the form of heat.
What are the three end stages of stars?
Three possible end stages of stars are:
- White dwarf. Initial mass of the star is less than 8 times mass of the Sun.
- Neutron star. Initial mass of the star is in between the 8 times mass of the Sun and 25 times mass of the Sun.
- Blackhole. Initial mass of the star is greater than 25 times mass of the Sun.
