what are the stages of the life cycle of a star?

As the core collapses, the outer layers of the star are expelled. A planetary nebula is formed by the outer layers. The core remains as a white dwarf and eventually cools to become a black dwarf. On the right of the illustration is the life cycle of a massive star (10 times or more the size of our Sun).

The life cycle of a frog consists of three stages: egg, larva, and adult. As the frog grows, it moves through these stages in a process known as metamorphosis.

The major stages of the human lifecycle include pregnancy, infancy, the toddler years, childhood, puberty, older adolescence, adulthood, middle age, and the senior years. Proper nutrition and exercise ensure health and wellness at each stage of the human lifecycle.

Cats Life Stages. Cats life cycle can be concluded basically to four stages of life, which are kitten, adolescent, adult and senior. Their behavior changes in every stages of life, as the age increases.

and corresponding developmental tasks. ∎The five stages are: growth, exploration, establishment, maintenance, and decline.

The overall lifespan of a star is determined by its mass. Since stars spend roughly 90% of their lives burning hydrogen into helium on the main sequence (MS), their 'main sequence lifetime' is also determined by their mass.

The fly life cycle has four stages. These stages move from eggs to larvae and pupae to adult. House flies have an incredible ability to reproduce, however, the fly lifespan is typically short. The life cycle of a fly begins with the egg.

Stars shine by burning hydrogen into helium in their cores, and later in their lives create heavier elements. Most stars have small amounts of heavier elements like carbon, nitrogen, oxygen and iron, which were created by stars that existed before them.

Complete metamorphosis is characterized by 4 life stages: egg, larva (caterpillar), pupa (cocoon), adult (butterfly). Usually, each of the life stages looks completely different from the other. Incomplete metamorphosis only has 3 stages, missing the pupa stage (hence, incomplete).

These stages are introduction, growth, maturity, saturation, and decline.

Stars about the size of our sun go through the same first four stages as does any other star. They begin their lives as a nebula, then become a Protostar, eventually becoming a main sequence star and finally a red giant.

After becoming distinct planets, they went through four stages of formation: Differentiation, Cratering, Flooding and Surface Evolution.
