collisions) and density in the core reinitiates nuclear fusion, equilibrium is achieved, and the cycle begins again at Step 1. Our sun is at the Main Sequence stage in its life. core shrinks and hydrogen fusion begins in the outer layers, – which then expands the entire star, turning it into a Red Giant.
Life Cycle of a Star. A star's life cycle is determined by its mass (i.e., the larger its mass, the shorter its life cycle). A star's mass is determined by the amount of matter in its nebula, the giant cloud of gas and dust from which a star was born. How is a star born? Over a very long period of time, the hydrogen gas in the nebula is
16 Mar 2009 Gravity causes dense cores in molecular clouds to collapse. •. Collapsing cores heat up. •. When core gets hot enough, fusion begins and stops the shrinking. •. New star achieves long-lasting state of balance. •. Sometimes protostars can drive an outflow (jets) of material. •. Protostars rotate rapidly, and
Life Cycle of Stars. Purpose. This activity enables students to demonstrate the life cycles of different types of stars, thereby illustrating the rarity of black hole-producing stars. Objectives. • Students will understand how and when black holes form. • Students will be able to describe the Sun as a star. • Students will be able to
smoothly in stars like our own Sun for billions of years. But how do the stars work? How are they born? How do they die? ACHIM WEISS at the MAX PLANCK. INSTITUTE FOR ASTRO-. PHYSICS in Garching tracks the life cycle of the cosmic plasma spheres – not with a telescope, but by using computer model calculations.

The star will now begin to shed its outer layers as a diffuse cloud called a planetary nebula. After the outer layers of the star have swollen into a red supergiant (i.e., a very big red giant), the core begins to yield to gravity and starts to shrink.
