QUESTION:

Problem 17SEQ

Explain answer clearly, with complete sentences and proper essay structure if needed.

Unenriched Stars. Suppose you discovered a star made purely of hydrogen and helium. How old do you think it would be? Explain.

ANSWER:

Solution 17SEQ:

Step 1 of 2:-

Here we have to verify the age of the star if is is made up of only hydrogen and helium.

In a star fusion reaction takes place all the time, where different nuclei fuse together and create heavy nuclei with a release of energy.

This is why a star shines and has a temperature.

With time the initial hydrogen gets converted into helium by fusion and later on into more heavier elements.
