What are the 5 stages of an average star?

What are the 5 stages of a star?

• 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 stages of a star?

Seven Main Stages of a Star

• Giant Gas Cloud. A star originates from a large cloud of gas.
• Protostar. When the gas particles in the molecular cloud run into each other, heat energy is produced.
• T-Tauri Phase.
• Main Sequence.
• Red Giant.
• The Fusion of Heavier Elements.
• Supernovae and Planetary Nebulae.

What is the life cycle of an average star?

Small or average stars usually last for several billion years as they burn their fuel slowly. A star the size of our Sun will spend around 10 billion years in this phase. After the main sequence phase, a star will turn into a red giant. It happens when helium builds up and the hydrogen fuel runs out.

What are the 3 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 our sun’s life cycle?

The Sun is currently a main sequence star and will remain so for another 4-5 billion years. It will then expand and cool to become a red giant, after which it will shrink and heat up again to become a white dwarf. The white dwarf star will run out of nuclear fuel and slowly cool down over many billions of years.

How are stars made step by step?

Stars form from an accumulation of gas and dust, which collapses due to gravity and starts to form stars. The process of star formation takes around a million years from the time the initial gas cloud starts to collapse until the star is created and shines like the Sun.

Is Antares an average star?

Antares (/ænˈtɛəriːz/), designated α Scorpii (Latinised to Alpha Scorpii), is on average the fifteenth-brightest star in the night sky, and the brightest object in the constellation of Scorpius.

What are the 5 stages of a low mass star?

Low mass star

• Main Sequence. Low mass stars spend billions of years fusing hydrogen to helium in their cores via the proton-proton chain.
• Red Giant. When hydrogen fusion can no longer happen in the core, gravity begins to collapse the core again.
• Planetary Nebula.
• White Dwarf.

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 stage of stars life is the longest?

The star is now on a stage of its life called the main sequences phase and is thus called a main sequence star. This is the longest phase of the star’s life and all the energy the star emits comes from the nuclear conversion of hydrogen to helium in its core. The time a star spends on the main sequence stage depends on its mass.

What is the life cycle of a low-mass star?

Low mass stars live out most of their lives as dim, small, and cool red dwarf stars. They last about 100 billion years, and in their last years they are a very hot, but dim white dwarf star.

What is the evolution stages of a star?

Stage 1 – Massive stars evolve in a simlar way to a small stars until it reaces its main sequence stage (see small stars, stages 1-4). The stars shine steadily until the hydrogen has fused to form helium ( it takes billions of years in a small star, but only millions in a massive star). Stage 2 – The massive star then becomes a Red Supergiant and starts of with a helium core surrounded by a shell of cooling, expanding gas. The massive star is much bigger in its expanding stage.

What are the stages in stars complete life cycle?

Life Cycle of a Star – Step by Step Explained Giant Gas Cloud. The life cycle of a star begins as a large gas cloud. Protostar. It is a baby star that forms when gas particles in the molecular cloud run into each other, and they create heat energy. T-Tauri Phase. Main sequence star. Expansion into Red Giant. The fusion of Heavier Elements. Supernovae and Planetary Nebulae.
