Stellar Evolution
1. This question has 4 part(s).
1.1. The table shows the 5 stages of the life cycle of a star that has a similar mass to the Sun.
Stage 1 | Initially, there is a massive cloud of dust and gas in space. |
Stage 2 | |
Stage 3 | Hydrogen nuclei join together to make helium nuclei |
Stage 4 | |
Stage 5 | The star eventually becomes unstable. An outer layer of dust and gas is ejected leaving behind a core. The core collapses due to gravity. |
(i) State and explain what happens in stage 2 of the diagram.
Include specific references to the relationships between
the masses of the bodies involved and the forces acting between them
the separation of the bodies involved and the forces acting between them
(ii) State and explain what happens in stage 4 of the diagram.
1.2. The timescale of stage 3 is in the order of
1.3. Explain why the star remains stable during stage 3 for the length of time you selected in part (b).
1.4. For stars with much larger masses than our Sun, stages 1 to 3 are almost exactly the same as lower mass stars. For the later stages, 4 and 5, the processes begin to differ.
Compare and contrast the final two stages in stars with much larger masses than our Sun and stars with similar masses to our Sun.
