each stage of star.
To understand further, answer the following questions below.
1. What element from space is pulled by gravity and turn into a protostar?
2. What will happen if a low massive main sequence star runs out of hydrogen
fuel?
3. How are heavy elements such as Carbon, Oxygen and Neon formed during
star formation?
4. Why is it impossible for any matter such as light and radiation to escape
from a black hole?
5. Why do you think massive star has shorter life span than average star?

3. After helium is exhausted in the core of a star, it will continue in a shell around the carbon-oxygen core. This can then form oxygen, neon, and heavier elements via the alpha process. In this way, the alpha process preferentially produces elements with even numbers of protons by the capture of helium nuclei.

4. Because of their vast, space-bending gravity. Everything that falls into them is ripped apart in an instant.

5. Massive stars live shorter lives than the common small stars because even though they have a larger amount of hydrogen for nuclear reactions, their rate of consuming their fuel is very much greater.
