1.In a main sequence star, what are the two forces (one inward and one outward) that are in equilibrium, keeping the star stable?
2.For a star like the Sun on the main sequence, what change gradually takes place in its composition as it ages, and where does this change occur?
3.What happens in the core of a dying star that causes it to leave the main sequence?
4.When a dying star goes through the phase called the “helium flash,” where is it on the main sequence, and what new thing is now happening in the core?

2)It starts to get bigger in the outer layers
3)Runs out of fuel for nuclear fusion
4)Not sure I am only 16, I don't know everything
