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.

Can the life cycle of a star be studied directly explain?

Basically, it is very difficult to pin down an individual star’s age. It has taken astronomers most of this century to piece together the life cycles of stars, simply because we cannot live long enough to follow a single star through its life cycle.

What is the star life cycle that is accurate?

The correct life cycle is: Star of one stellar mass, red giant, white dwarf, planetary nebula.

What are the stages of Star Life?

The stages of most stars life in order are: A Protostar , Main Sequence, Red Giant B Protostar, Main Sequence, Red Dwarf C Main Sequence, Red Dwarf , Protostar D Red Giant, Main Sequence, Protostar E Nebula , Protostar, Red Dwarf. 2 What does a protostar have to do to become a star? A Nuclear fusion in its core. B Nuclear fission in its core.

What is the first stage of a star?

The first stage in the birth of a star is called a protostar. This is where the majority of the stellar material has collected together in ball in the center, but there is a huge disk of gas and dust obscuring it from our view.

What are the stages of stars?

Stars go through many stages throughout their lives in in our Universe. Stage one: Stars form from mainly gas and dust. Stage two: Gravity pushes the dust particles causing them to spiral together, the gravitional energy is converted into heat energy causing the temperature to rise.

What is the cycle of a star?

The life cycle of a star is determined by its mass. The larger the mass of a star the shorter will be its life cycle. The life of a star ranges from a few million years to a billion years, depending on the mass. It is believed that stars are born from collapsing dense clouds of dust and gas found in spiral galaxies.
