Start studying life cycle of a star.

Lifecycle of a star diagram. The temperature increases from right to left backward from most charts you may be used to using. Students will complete a diagram to help them visualize the life and death of a star. The sun has a surface temperature of 5500 degrees celcius its colour appears yellow.

The h r diagram uses a ratio scale. On the right of the illustration is the life cycle of a massive star 10 times or more the size of our sun. Stars give off large amounts of energy in the form of electromagnetic radiation.

Nuclear reactions at the centre or core of stars provides enough energy to make them shine brightly for many years. Cloud of gas and dust. The colour of a star is determined by its temperature the hottest stars are blue and the coolest stars are red.

Produces heat and light. Like low mass stars high mass stars are born in nebulae and evolve and live in the main sequence. A star is ball of plasma undergoing nuclear fusion.

Process where smaller nuclei such as hydrogen fuse to form larger nuclei such as helium. Bell ringer notes star life cycle h r diagram binders due tomorrow what is a star. Explosive death of a star.

However their life cycles start to differ after the red giant phase. As the core runs out of hydrogen and then helium the core contacts and the outer layers expand cool and become less bright. Stellar evolution is the process by which a star changes over the course of time.

Use this astronomy worksheet to learn about the stages in the life cycle of a star. The energy produced by the star is by nuclear fusion in the stars core. Where stars are born.

Life cycle of star. Each evenly spaced mark represents a temperature twice that of its neighbor to the right. The x axis of the h r diagram indicates the stars surface temperature in degrees kelvin.

Depending on the mass of the star its lifetime can range from a few million years for the most massive to trillions of years for the least massive which is considerably longer than the age of the universethe table shows the lifetimes of stars as a function of their masses. Life cycles of stars. This is a red giant or a red super giant depending on the initial mass of the star.

The brightness is measured in magnitude. Life cycle of a star stars are formed in clouds of gas and dust known as nebulae.
