Hydrogen shell fusion
WebA hydrogen burning shell forms around the helium core, and the shell contributes more and more helium to the core over time. Eventually the core becomes hotter and denser … WebA) It is fusing hydrogen into helium in the core. B) It is fusing hydrogen into helium in a shell outside the core. C) It is fusing helium into carbon in the core. D) It is fusing helium into carbon in a shell outside the core. E) It is not fusing any element; it is contracting and heating up. Answer: B
Hydrogen shell fusion

WebNew energy produced by fusion of this hydrogen now pours outward from this shell and begins to heat up layers of the star farther out, causing them to expand. Meanwhile, the helium core continues to contract, producing more heat right around it. This leads to more fusion in the shell of fresh hydrogen outside the core (Figure 22.2).
