Representative lifetimes of stars as a function of their masses · Artist's depiction of the life cycle of a Sun-like star, starting as a main-sequence star at ... Life Cycles of Stars A star's life cycle is determined by its mass. The larger its mass, the shorter its life cycle. A star's mass is determined by the amount of matter that is available in its nebula, the giant cloud of gas and dust from which it was born.Over time, the hydrogen gas in the nebula is pulled together by gravity and it begins to spin. As the gas spins faster, it heats up and ...

Life cycle of a star diagram

Life Cycle of a Star like our Sun… •Our sun is at the Main Sequence stage in its life. –When the hydrogen in the core has been used up, the core shrinks and hydrogen fusion begins in the outer layers, –which then expands the entire star, turning it into a Red Giant. –The sun begins to die when helium is fusing into other •The aging star has become a red giant star, and can be 100 times larger than it was in its main sequence phase •When this hydrogen fuel is used up, further shells of helium and even heavier elements can be consumed in fusion reactions •The red giant phase of a star’s life will only last a few hundred million years before it runs out of ... H-R diagrams which show how a star changes or evolves during its stellar life. The H-R diagram can be used to study and understand how a star will evolve during ...

Life cycle of stars and the Hertzsprung-Russel Diagram Describe and explain an HR diagram. Use an HR diagram to explain the evolutionary path of a Star of given mass. Understand the life-time of a star of differing spectral classes Hertzsprung-Russel Diagram A graph of absolute magnitude versus spectral class of a star is known The life cycle for a particular star depends on its size. The diagram shows the life cycles of stars that are: ... Flow chart showing the life cycle of a star, ... Star in a Box allows you to explore one of the most enigmatic tools in astronomy - the Hertzsprung-Russell diagram. When you first open the box you start with a star with the same mass as the Sun but you can change this to a different mass at any time. The tracks that you see on the graph (on the left) map the lifecycle of the star. Life Cycle of a Star ... Stars are formed in clouds of gas and dust, known as nebulae. Nuclear reactions at the centre (or core) of stars provides enough energy ...

Stars go through a natural cycle, much like any living beings. This cycle begins with birth, expands through a lifespan characterized by change and growth, and ultimately leads to death. The time frame in the life cycle of stars is entirely different from the life cycle of a living being, lasting in the order of billions of years. Star Life Cycle Worksheet Draw a line between the correct definition for each type of star or scientific term from the options below. One has been done for you. 1. Black dwarf B. A. A place in space where new stars are formed 2. Black hole B. A cloud of gas and dust in outer space 3. Stellar nursery C. A small and relatively cool star 4. Nebula D.
