Nuclear burning rates vs temperature

What you are seeing: the energy generation rate $\varepsilon$ for the three dominant burning channels as a function of central temperature. The CNO cycle crosses over the pp chain near $T \sim 2 \times 10^7$ K.

WHAT TO TRY

Vary each control and watch the rail readouts respond.
Compare the diagnostic plot against the live scene.
