Chapter 2: Protostellar collapse and star formation

Chapter 2: Protostellar collapse and star formation. One of 3 branches of proton-proton chain. CNO cycle: C, N O atoms act as catalysts. T-dependence of pp chain and CNO cycle. Hydrostatic equilibrium: negative feedback loop. If core T drops, fusion rate drops, core contracts heats up.
